By increasing application precision and reducing unneeded applications, water can be conserved and energy can be saved. Nutrient Management. Nutrient management is a conservation practice that involves proper timing and placement of the right amounts of nutrients and soil amendments for adequate soil fertility and to minimize potential environmental degradation, particularly of water quality. Crop Residue Management.
No-till is a conservation practice that leaves the crop residue undisturbed from harvest through planting except for narrow strips that cause minimal soil disturbance. Crop residues are materials left in an agricultural field after the crop has been harvested.
These residues include stalks and stubble stems , leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of erosion.
No-till can be used for almost any crop in almost any soil and can save producers labor costs and fuel. Natural Resources Conservation Service. Stay Connected. Loading Tree Under severe climatic conditions, selected roadside trees can form wind breaks and shelter belts to protect crops, and help to reduce climatic excesses and soil erosion. They can restore some ecological diversity to areas of agricultural monotony.
They can be used by bees to produce honey and wax. Explanation: 1] it restricts soil erosion. A windbreak shelterbelt is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion.
They are commonly planted in hedgerows around the edges of fields on farms. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

It is also advisable to fence out a belt to prevent stock grazing on the lower limbs of vegetation and creating gaps.
If gaps occur within a belt, wind will tunnel through the gaps at an accelerated rate. This can result in blowouts near the gaps and also be detrimental to stock and crops. Wind speed accelerates around the ends of shelterbelts. By increasing the length of the belts or joining them to other belts this impact is reduced.
Belts can be joined where they can form a right angle for protection from a range of wind directions as illustrated in Figure 1. Stock should not be able to graze below or at the ends of a shelterbelt as these areas are very susceptible to erosion. The more effective a belt is in reducing wind erosion, the more eroded the sites at the end of the belt can be, unless the ground surface is protected. Bird, P. Agroforestry Systems Brandle, J.

Impacts of wind erosion on crops Nutrients lost due to soil erosion by wind must be purchased and replaced to avoid productivity losses. Wind erosion can have a direct impact on crops in several ways, including: exposing plant roots burying plants under moving soils blowing plants out of the ground. Nutrients in topsoils Most soil nutrients are held in the organic matter of plants and in the top layer of soils. Protecting soils with vegetation Soils are most vulnerable: if they have been heavily grazed or cultivated during dry or drought conditions.
Dry conditions result in low vegetative cover because of slow growth and overstocking.
