Question

Planting ___ on field bunds to strengthen them and make the soil

Nitrogen rich.​

Answer 1

Answer:

Plants that contribute to nitrogen fixation include the legume family – Fabaceae – with taxa such as clover, soybeans, alfalfa, lupins, peanuts, and rooibos.

Answer 2

Answer:

Gliricidia

Explanation:

• The genus Gliricidia belonging to the family Leguminosae is a small, fast-growing, tropical thornless plant. It is a nitrogen-fixing tree.

• Soils in the tropics are low in the organic matter thus have a low nutrient supply capacity. Green leaf manure plants like Gliricidia play a vital role in increasing soil fertility. Growing Gliricidia plants on farm bunds serve the dual purpose of production of green leaf manure rich in N content, under field conditions. Also, it helps in soil conservation through reduced soil erosion.

Hence planting Gliricidia on field bunds to strengthen them and make the soil nitrogen-rich.
