What was the benefit from crop rotation?

Answer 1

If you rotate your crops every year, then the soil will have more nutrience in it. If you just have one crop all the time the crop will eat up all of one nutrient that it needs the most, but if you rotate it then it will keep the nutrient level balanced.

answer

while the above answer is mostly true it isn't quite accurate. the main reason for crop rotation is to prevent the accumulation of specific crop pests and disease. if you grow the same crop in the same area over and over the soil will accumulate organisms which target this crop most efficiently but if you rotate your crops a specific pathogen will not be able to sustain it self when its host is replaced by a different crop.

as for the nutrients, if one includes legumes in the crop rotation and does not harvest them but chops them into the ground one enriches the soil with nitrogen which is the main nutrient missing for plant growth how ever this does not replace the use of pottasion and phosphoros which are the other main plant nutrients, these need to be suplamented with the application of fertilizers and compost be it organic farming or regular. zaf.

Answer 2

Diffrent crops absorb difrent type of nutrients from the soil so if one plant is planted all year round the soil may become drained of certain nutrients that are requeired. So in order to replace them rotational farming is nescesary.and also to prevent insects ,parasites and fungus to invade as some only thrive on certain pants when another crop is planted they kill each other . Or also simply because difrent crops grow at diffrent times of the year seasonal rotation.

Answer 3

Planting different crops each year is called crop rotation. It is important because it gives the land time to recover from a depletion of type f nutrient, and makes for healthier crops.
