crop rotation definition for class 9

In fixed rotation when they not only recur in a fixed order but also at regular intervals. Such frequent cultivation may tend to reduce the organic matter of the soil. (2) Supplies organic matter and nitrogen. The wheat straw makes good bedding, while the wheat may either sold exchanged for concentrates. Definition? [8], A great advantage of crop rotation comes from the interrelationship of nitrogen-fixing crops with nitrogen-demanding crops. Under the two-field system, if one has a total of 600 acres (2.4 km2) of fertile land, one would only plant 300 acres. Crimson clover may be seeded in the tomatoes at the last cultivation, and growth turned under the following spring for the benefit of a succeeding crop. Tillage is meant to inhibit growth of weeds by overturning the soil; however, this has a countering effect of exposing weed seeds that may have gotten buried and burying valuable crop seeds. In turn, oats or barley are removed from the land in ample time for seeding winter wheat. One strong point in this rotation is that one plowing answers for three crops. Wherever feasible, a large proportion of the product of rotation should be food for livestock. In the standard rotations, eight tons of manure per acre were applied during the rotation. But they entail additional labor in the process of cultivation. Crops that are costly to establish, such as alfalfa, should occupy the land for two or more years in order to minimize the annual cost of production. (5) It provides for the economic destruction of weeds. [9] Decisions about rotations are made years prior, seasons prior, or even at the last minute when an opportunity to increase profits or soil quality presents itself.[8]. Crop rotation definition: the system of growing a sequence of different crops on the same ground so as to maintain... | Meaning, pronunciation, translations and examples Legumes, like alfalfa and clover, collect available nitrogen from the atmosphere and store it in nodules on their root structure. Rotating crops adds nutrients to the soil. And crops in the rotation unless two crops can be harvested from the land in one year. [9] With much of the soil around the plant exposed to disruption by rainfall and traffic, fields with row crops experience faster break down of organic matter by microbes, leaving fewer nutrients for future plants. The plot is at the far end from the lime and manure acidifies the soil so … Crop protection is the general method or the practice of protecting the crop yields from different agents including pests, weeds, plant diseases, and other organisms that cause damage to the agricultural crops. Clover hay supplies the protein in which corn is deficient, thus giving & well-balanced ration. Corn prices are prevailing. Every seventh year they would not till, prune or even control insects.[3]. How much nitrogen made available to the plants depends on factors such as the kind of legume, the effectiveness of rhizobia bacteria, soil conditions, and the availability of elements necessary for plant food.[20]. So, where "active" soil organic matter is a key to productive soil, soil with low microbial activity provides significantly fewer nutrients to plants; this is true even though the quantity of biomass left in the soil may be the same. This principle is of particular use in organic farming, where pest control must be achieved without synthetic pesticides. And the other as the minor rotation. D. None of these. [10] Green manure of legumes is an excellent source of nitrogen, especially for organic systems, however, legume biomass does not contribute to lasting soil organic matter like grasses do. Between the seeding time of oats and the time for planting corn, there is sufficient time to prepare the land for the latter crop. And clovers that follow the grain crops. Growing the same crop in the same place for many years in a row, known as monocropping, gradually depletes the soil of certain nutrients and selects for a highly competitive pest and weed community. Notwithstanding these facts, certain crops leave the land in poorer conditions for subsequent crops than it was before. In the northeastern part of the United States, a rotation of corn, oats, wheat, and hay with various modifications dominates most of the general and livestock types of farming. One section was planted in the autumn with rye or winter wheat, followed by spring oats or barley; the second section grew crops such as peas, lentils, or beans; and the third field was left fallow.

C. Who do not have sufficient land for farming. For example, land that has been long in grass sometimes becomes so infested with wire-worms as to cause a practical failure when devoted to corn. Ancient Near Eastern farmers practiced crop rotation in 6000 BC without understanding the chemistry, alternately planting legumes and cereals. Cereal and grasses are frequent cover crops because of the many advantages they supply to soil quality and structure. It calls for a eight simple crops: tomatoes, peas, cabbage, sweet corn, potatoes, squash, root crops, and beans. A good rotation of crops will enable the farmer to do a larger proportion of his own work than would be possible if the land was devoted to one crop. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pest and weeds.
