A harrow is afarm tool. It is an implement for breaking up and smoothing out the surface of the soil. In this way it is different from a plow,which cuts deeper into the soil.
What is the purpose of using a Harrow?
Harrow, farm implement used to pulverize soil, break up crop residues, uproot weeds, and cover seed. In Neolithic times, soil was harrowed, or cultivated, with tree branches; shaped wooden harrows were used by the Egyptians and other ancient peoples, and the Romans made harrows with iron teeth. Modern harrows comprise several varieties.
What does harrowing mean in agriculture?
Harrowing Definition The definition of harrowing is a soil preparation method that is often used in conjunction with plowing to ready a field for seeding. Harrowing is performed with a harrow, and it is sometimes confused with plowing, as they may appear similar at first, but plows go deeper into the soil and are typically wider.
What is the difference between a Harrow and a plow?
Harrows are not directly related to plows in design, but they have a joint application, as harrowing is usually performed right after a field has been plowed. Let’s take a look at some of the imperfections that can be improved by harrowing, especially after the soil has just been plowed. How Does Harrowing Benefit Soil?
What type of Harrow is best for harvesting?
Heavier chains, on the other hand, will bring heavy clods out of the ground to the surface. Chain-disc harrows are some of the most efficient harrow types because they can typically prepare a field in a single pass. While chain-disc harrows aren’t very versatile, they are excellent at smoothing out the upper layer of the soil.
How Does Harrowing Benefit Soil?
From preparing your crops for seeding to ensuring that weeds don’t grow, you’ll want to make sure that you harrow your soil whenever possible .
How to get rid of clumps in soil?
Harrowing is one of the best ways to eliminate clumps. Most of the time, excessive clumping in soil is caused by plowing, which is why you’ll usually want to follow up your plowing job with the harrow. In addition to removing clumps from your soil, a harrow is an excellent tool for breaking up sod and mixing it into the surrounding ground.

What is a disc harrow?
The disc harrow is made up of a row of vertically-aligned discs which run through the soil as they are dragged along. These harrows are typically used to break up clods of earth and provide a sort of midpoint between a plow and other, lighter kinds of harrows, like the chain harrow.
What is the best way to plant seeds?
Tilling. Of course, harrowing is a form of tilling, and it is one of the most effective final measures to use before you plant your seeds. Since harrows provide a fine, even layer of soil, your crop rows will be ready for seeding much faster than they would if you used a rougher method.
What is the best tool to break up sod?
In addition to removing clumps from your soil, a harrow is an excellent tool for breaking up sod and mixing it into the surrounding ground. Bigger clumps will be harder for the harrow to break up, but it can help bring them up to the surface of the soil where it will slowly be eroded away.

What is a preemergence harrow?
Preemergence harrowing kills the weeds from white thread to the cotyledon stage. However, operating speed and tines can be adjusted to work the harrow more vigorously and kill bigger weeds in deep-rooted crops such as beans, peas, sweet maize, and spinach ( Van der Weide et al., 2008 ). The adjustment of operating speed and tine could control the small-seeded broad-leaved weeds having 2–4 true leaves up to 90% ( Van der Weide and Kurstjens, 1996 ). For postemergence harrowing, spring tine harrows are used in different crops such as cereals ( Rasmussen and Ascard, 1995 ), maize ( Baumann, 1992 ), potatoes ( Rasmussen, 2002 ), peas, beans and many transplanted vegetables, sugar beet ( Hallefalt et al., 1998 ), and carrots ( Fogelberg, 2007 ). Harrowing cannot be practiced in sensitive crops such as sugar beet before the four-leaved stage of the crop ( Ascard and Bellinder, 1996; Westerdijk et al., 1997 ). Various initiatives have also been started in different countries to promote harrowing in the rising trend of herbicide use and associated risks. For example, farmers are subsidized for using harrowing in parts of Norway ( Fylkesmannen, 2011 ).
What is a weed harrow?
Weed harrowing, a mechanical weed control method , is being used for weed control since the 20th century (Korsmo, 1926 ). Harrowing is a mechanical cultivation method applied to both crop and weed plants. Harrows are contiguous weeders working in both the intrarow and interrow. Weed harrows have undergone intensive modernization with respect to tine depth and angle; however, their applicability to early crop stages is still limited ( Van der Weide et al., 2008 ). Modern spring tine harrows were designed for weeding dicot weeds in monocot crops, that is, cereals. In cereals, their use at early crop stages is generally not problematic if done carefully. When used in dicot arable crops, for example, peas, beans, and linseed, much greater care is required at early crop stages and often all crop stages. Spring tine harrows can also be used in some vegetable crops. Working principle and selectivity of harrows have been described in detail by Kurstjens and Kropff (2001), Kurstjens (2002), and Cirujeda et al. (2003). Typical mechanical harrows and their components used in different regions of the world are shown in Figs. 8.8–8.10. Harrowing can be practiced either as preemergence or during postemergence stages of crop plants. Preemergence harrowing is gentle and applied to deeply sown crops. Postemergence harrowing is capable of controlling small weeds, which have not passed their first true-leaf stage ( Van der Weide et al., 2008 ).
What are the drawbacks of weed harrowing?
The drawbacks associated with weed harrowing, especially control failures against tap-rooted and tall-growing weed species, and the risk of crop injuries have motivated stakeholders to look for selective mechanical methods. Selectivity in the sense that only weeds are mechanically impacted, while the crop is left untouched, is only achievable if the cultivated zone is separated from the crop row. Widening the interrow spacing of winter wheat to 20–25 cm will allow a hoe blade to be operated selectively between the cereal rows. Hoe blades are more aggressive than tines and add a cutting action to the mechanisms of weed control. The result is higher effectiveness against problematic weed species such as grasses and tap-rooted species with an erect growth habit ( Melander et al., 2001, 2003 ). Timing of treatment is less crucial with interrow hoeing than weed harrowing because the cutting action of the blades also controls weeds with more than two to three true leaves. There is some evidence that perennial weeds, notably C. arvense, can be hampered by the removal of aboveground shoots ( Graglia et al., 2006 ). It will not eradicate a perennial weed problem since belowground propagules are not affected directly; however, shoot removal will stimulate resprouting depleting the food reserves of belowground organs. At the same time, translocation of photosynthetic assimilates to roots and rhizomes is interrupted, and overall, these effects can impede the regenerative capacity of perennial weeds.
What does harrowing do to a field?
Harrowing breaks up the droppings and spreads the manure more evenly across the field, helping prevent the highly localized, lush, rank growth of roughs.
How to control wireworms in soil?
Mechanical methods of disturbing the soil, such as plowing, harrowing, disking, and rotovating are known to reduce various stages of wireworms (Thomas 1940, Parker and Howard 2001 ), and although not a primary control method can sometimes be considered part of an IPM program. The objective of cultivation is to directly destroy eggs, larvae, pupae, and adults in the soil, or indirectly kill them by bringing them to the surface and exposing them to heat or to natural enemies such as birds and arthropod predators ( Thomas 1940, Seal et al. 1992 ). Pupae of many wireworm species, which are very soft-bodied and generally found in the upper 38 cm of soil during July and August, are particularly vulnerable to shallow plowing, and up to 90% mortality has been reported ( Andrews et al. 2008 ). Cultivation at that time might also expose eggs and small larvae to desiccation and mechanical injury ( Thomas 1940 ). Some reductions in larger wireworms by cultivation have been reported, and a 91% drop in wireworms caught in traps occurred when soil was plowed three times during the summer ( Seal et al. 1992 ). The aforementioned studies, however, were conducted in fallowed fields during summer months, which are not typical field conditions available to most growers. In the UK, where summer cultivation is not possible, cultivation practices are thought to be most effective in reducing wireworm populations if done in the autumn when wireworms are active near the soil surface ( Gratwick 1989 ).
How to control spreading latrines?
There are three main ways of controlling the development of spreading latrines: through harrowing, removal of droppings or managed latrines . Harrowing breaks up the droppings and spreads the manure more evenly across the field, helping prevent the highly localized, lush, rank growth of roughs. As harrowing spreads the manure, it also spreads internal parasites (e.g., worms) around the pasture. However, harrowing undertaken in warm, dry weather should result in desiccation of the droppings and the demise of the parasites. After harrowing, the pasture needs to be rested, often for 6 weeks or more, (a) to allow the manure dry out and kill the parasites and (b) for the manure to biodegrade and the surrounding pasture become palatable once again for horses. In addition to breaking up and spreading manure, harrowing also aerates the soil, pulls out dead grass, weeds etc. and through gently disturbing the soil surface can release minerals that can then be utilized by the growing plants.
How to broadcast seed?
Broadcast seeding requires that the soil be prepared by clean plowing, disking, harrowing, and (in some cases, but not all) compaction to produce a smooth, firm seedbed. The seed may then be broadcast on the surface using any one of a number of methods. When the seeding is completed, however, the surface must be rolled or compacted with a corregated roller for best results. Dragging a spike-tooth harrow over the field, either while seeding or after it is completed, causes some covering of the seed. Because firmness and a high degree of soil-seed contact may be lacking in this procedure, the percentage of the seeds that result in established seedlings will be reduced. This practice requires a higher seeding rate than do other methods to obtain an equivalent stand. A very good broadcast seeding system has been developed by the Brillion Company ( Fig. 9.1) that combines the compacting and seeding operation. The machine is fairly costly, but in a situation in which large areas are being seeded annually, it may be an economical investment. The seed is dropped from the seed box, down between the two sets of corregated rollers. The first or forward set firms the soil originally, the seed is dropped on the surface, and the second set presses the seeds into the soil and firms it further. Broadcast seeding results are equally as good as other methods if this procedure is followed.
