How do farmer improve the nitrogen content in the soil?
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose …
How can we solve the problem of fertilizer?
The quickest way to solve this problem is to ignore the weight of the fertilizer bag and simply divide the amount of nitrogen desired (1.0 lb nitrogen per 1000 sq ft) by the percentage of nitrogen in the bag (26\%).
What are the possible problems that the farmers can encounter when applying phosphate fertilizers in the pond what are the possible solutions to these problems?
The disconnection between livestock and land is behind some of these imbalances in phosphorus use. Optimising the use of land for food and livestock in ecological farming systems will help in using nutrients efficiently and avoiding massive losses of phosphorus (and other nutrients) into the environment.
How would you improve or maintain soil fertility?
Organic farmers seek to “build the soil” or enhance its inherent fertility by using crop rotations, animal and green manures, and cover crops. Crop rotation and tillage practices must provide an appropriate seedbed and pest control while minimizing erosion.
How do farmers apply nitrogen?
Farmers apply nutrients on their fields in the form of chemical fertilizers and animal manure, which provide crops with the nitrogen and phosphorus necessary to grow and produce the food we eat.
What is the major problem with nitrogen fertilizers?
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.
How can farmers reduce pollution?
Farmers can reduce NPS pollution from irrigation by improving water use efficiency. They can measure actual crop needs and apply only the amount of water required. Farmers may also choose to convert irrigation systems to higher efficiency equipment.
What are fertilizer related problems?
Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well.
How can farmers prevent agricultural runoff?
Planting trees, shrubs and grasses along the edges of your fields to add as a conservation buffer can help prevent any runoff. This is especially helpful if you have a field that borders any body of water.
What do farmers spread on fields?
Generally, the most common source of odour complaints relate to the storing and spreading of bio-solids (sewage sludge), animal manures and slurries (muck spreading). Prevailing winds can carry these odours some distance across fields and into residential areas.
How can farmers improve soil quality?
Management Practices to Improve Soil Health
- Reduce Inversion Tillage and Soil Traffic. Excessive tillage is harmful to soil health in a number of ways.
- Increase Organic Matter Inputs.
- Use Cover Crops.
- Reduce Pesticide Use and Provide Habitat for Beneficial Organisms.
- Rotate Crops.
- Manage Nutrients.
Why do farmers rotate their crops?
A crop rotation can help to manage your soil and fertility, reduce erosion, improve your soil’s health, and increase nutrients available for crops.
How big is Punjab’s wheat crop?
Field data reveal a yield estimate of 20.04 million tonnes for Punjab, about 3\% higher than Punjab Crop Reporting Service’s estimate of 19.37 million tonnes. Using multi-year field data as a calibration input, the GLAD team will next develop a Landsat-based model to estimate wheat yield and production for Punjab.
What is the productivity of wheat in India?
The productivity of wheat which was 2602 kg/hectare in 2004-05 has increased to 3140 kg/hectare in 2011-12. The major increase in the productivity of wheat has been observed in the states of Haryana, Punjab and Uttar Pradesh.
What is the zinc deficiency in soil in India?
The work conducted under the All India Coordinated Research Project on Micronutrient in Crops and Soils, has shown wide spread deficiency of zinc in soils in India. At the national level, the deficiency level in micro nutrients is Zn: 46 \%, B: 17 \%, Mo: 12 \%, Fe: 11 \% and Cu: 5\%.
Why is durum wheat not marketed in India?
Most Indian durum is not marketed separately due to segregation problems in the market yards. However, some quantities are purchased by the private trade at a price premium, mainly for processing of higher value/branded products. The production and productivity of Wheat crop were quite low, when India became independent in 1947.
