Question

essay on leveller in agriculture​

Answer 1

Answer:

Land levelling is a measure used in surface irrigation, such as basin and furrow irrigation. It consists of:

preparing the irrigation plot in a way that no high and/or low spots disturb the uniform distribution of irrigation water on the field, and

ensuring the optimal slope for water movement across a field when irrigated.

Levelling results in more efficient irrigation and, if fertigation and chemigation are applied, in more efficient use of fertilizers and pesticides. In an unlevelled field, high spots might not be covered by irrigation water, and the dissolved nutrients and/or pesticides might percolate unused into the soil. In case of low spots, water and the dissolved nutrients and chemicals might accumulate there and create zones of water logging and nutrient or pesticide accumulation. This in turn will disturb soil aeration and water uptake by crops. In either case, the uniformity of the crop cover is disturbed and yields might decrease.
