Explanation:
2-Drip irrigation systems dispense water in a controlled manner. Using a series of long plastic pipes, drip irrigation is usually low to the ground, so less water is lost to runoff and evaporation. At regular intervals, or depending on the yard design, there are openings in the irrigation pipes to allow water to come out.
In contrast, a sprinkler system spreads water in more widespread, controlled ranges. While a drip irrigation system is above ground, when it comes to sprinklers, the pipes are underground with only the sprinkler heads visible above ground.
3-
Weeds are the unwanted plants which grow along the main plants and compete with water , minerals , nutrients etc.
Examples :- Xanthium , fieldbindweed , Quack grass etc.
Weedicides are the chemicals which help in killing the weeds which acts like a manure.
4-Crop rotation means the practice of growing different crops in succession on the land chiefly to preserve the productive capacity of soil.
Mixed cultivation is an agricultural system in which a farmer conduct different agricultural practice together, such as cash crops and livestock.
1-Natural fertilizers improve the texture of the soil and increase the amount of beneficial microorganisms. A wider range of chemical fertilizers specific to certain plant types are more readily available at home and garden centers than are natural fertilizers
Common chemical fertilizers are mass-produced and sold in bags, boxes, bottles and in bulk, in liquid, powder, granules, and pellets or in spikes. This type of fertilizer usually has a higher level and a larger percentage of soluble nitrogen than do natural fertilizers. However, chemical fertilizers are often tailored to specific plant types, or for a specific purpose, such as accelerated growth
Explanation:
Natural Fertilizers: Natural fertilizers are those formed through decomposition
Chemical fertilizers: chemical fertilizers are manmade or mined
Drip irrigation: drip irrigation system is above ground
Sprinkler: the pipes are underground with only the sprinkler heads visible above ground.
Weeding: Weeding is the process of killing or removal of weeds.
Weedicides: Weedicides are the chemicals used to kill weeds
Multi Cultivation: Mixed cultivation is an agricultural system in which a farmer conduct different agricultural practice together, such as cash crops and livestock.
Crop Rotation: Crop rotation means the practice of growing different crops in succession on the land chiefly to preserve the productive capacity of soil.
