Question: What Is High Residue In Farming?

What are high residue crops?

Winter cereals typically used as high – residue cover crops include rye (Secale cereal), black oats (Avena strigosa), wheat (Triticum), or triticale (Triticosecale). Similar to other cover crops, high – residue cover crops require a termination operation to kill the crop before planting the cash crop.

Which crop generates maximum residue?

Among different crops, cereals generate maximum residues (352 Mt), followed by fibres (66 Mt), oilseeds (29 Mt), pulses (13 Mt) and sugarcane (12 Mt). Cereal crops (rice, wheat, maize, millets) contribute 70%, while rice crop alone contributes 34% to the crop residues.

Is Straw a crop residue?

As a byproduct of grain production these residues have been called waste, yet research has shown their nutrient, erosion, and soil carbon characteristics have value that must not be overlooked. Crop residues of interest for bioenergy include; corn stover, corn cobs, wheat straw, soybean straw, and rice hulls.

What is the impact of leaving crop residues on the soil surface?

Leaving crop residue on the soil surface improves nutrient cycling and, ultimately, soil quality that will increase and sustain soil productivity. Through conservation practices that include balanced residue management and soil fertility, environmental quality can be substantially enhanced.

Why do farmers burn crop residue?

Paddy residue left by harvesters takes one-and-half months to decompose while farmers don’t have sufficient time to sow their next crop, wheat. Stubble burning is a quick, cheap and efficient way to prepare soil bed for wheat, the next crop.

How do you manage crop residue?

There are two different ways to manage crop residues. The first method is tillage prior planting when plant residues are incorporated into the soil. Another modern farming practice is reduced tillage or no-till farming, where crop residues are left on the surface and planting is carried out without soil tillage.

How does crop residue help in organic farming?

Crop residues can improve soil structure, increase organic matter content in the soil, reduce evaporation, and help fix CO2 in the soil. Good residue management practices on agricultural lands have many positive impacts on soil quality. Besides, crop residues can be used in biofuel production.

What is crop residue cover?

Save ENERGY, Save MONEY. Conservation tillage systems have at least 30 percent of last year’s crop residue on the soil at planting. Residue adequately controls erosion by both wind and water, among other conservation benefits. Crop residues are materials left in an agricultural field after the crop has been harvested.

What is on site residue management?

Crop residue management through conservation agriculture can improve soil productivity and crop production by maintaining SOM levels. Greater microbial biomass and activity near the soil surface acts as a reservoir for nutrients needed in crop production and increases structural stability for increased infiltration.

What is left after a crop is harvested is called crop?

There are two types of agricultural crop residues. Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves, and seed pods. These residues include husks, seeds, bagasse, molasses and roots.

Is crop residue toxic waste?

The main adverse effects of crop residue burning include the emission of greenhouse gases (GHGs) that contributes to the global warming, increased levels of particulate matter (PM) and smog that cause health hazards, loss of biodiversity of agricultural lands, and the deterioration of soil fertility [22].

How is crop residue measured?

Use a 50- to 100-foot tape measure (or a rope with marks spaced at 1-foot intervals). Stretch the tape (or rope) between two stakes placed diagonally (at a 45 degree angle) of the crop rows. Looking directly from above the tape (vertically), count the number of times where a “foot” mark intersects with crop residue.

Why is crop residue incorporated back into the soil before planting the next crop?

Leaving crop residue on the surface of the soil is an investment. The near-term return is a savings in moisture with a payback in better yields. “ Residue and growing vegetation protect the soil surface from erosion by absorbing the impact energy of raindrops, thus, reducing the movement of soil particles,” says Jasa.

How does crop residue conserve soil and water?

Crop residue protects the soil surface from erosion by absorbing the impact energy of water droplets, thus reducing soil particle detachment. Soil particle detachment can cause crusting and sealing of the soil surface which results in decreased infiltration and increased runoff.
