What is the disadvantage of alley cropping?
One disadvantage of alley cropping is that additional labor is required to prune/coppice the trees. Rows of trees reduce wind speed, thereby controlling wind erosion. They also create sheltered microclimates that improves the yield and quality of crops growing in the alleys. Wildlife.

What is alley cropping used for?
Alley cropping, also sometimes referred to as “intercropping”, is the practice of planting rows of trees with a companion crop in between. Frequently this can be used to add another cash crop but it also reduces surface water runoff and erosion, improves soil health and fertility, and reduces wind erosion.
Where does alley cropping occur?
Alley cropping is an agroforestry practice that places trees within agricultural cropland systems. This system is sometimes called intercropping, especially in tropical areas. It is especially attractive to producers interested in growing multiple crops on the same acreage to improve whole-farm yield.
How does alley cropping reduce soil erosion?
Rows of trees reduce wind speed, thereby controlling wind erosion. They also create sheltered microclimates that improves the yield and quality of crops growing in the alleys.
How does alley cropping prevent soil erosion and increase soil fertility?
USDA Natural Resources Conservation Services. Alley Cropping: Practice Introduction, practice code 311. The hedgerow/alley system uses land and resources in an efficient way in that it improves soil structure and minimizes soil erosion by reducing surface runoff velocities and prolonging infiltration rates.
How does alley cropping prevent pests?
Alley cropping can help ward off pests. According to the Center for Agroforestry, “Alley cropping reduces damage from insect pests by reducing crop visibility, diluting pest hosts due to plant diversity, interfering with pest movement, and creating habitat more favorable to beneficial insects.”
What is the major advantage of alley cropping over the traditional shifting cultivation?
The suppression of weeds is therefore viewed as a major advantage of alley cropping, especially in small scale farming where weeding can take more than 30 % of the l~bor used in crop production.
What is the positive impacts of alley cropping in landscape?
Alley Cropping can help diversify farm enterprises, protect soil, improve air and water quality, enhance fish and wildlife habitat, conserve biodiversity, and beautify the landscape.
Why is alley cropping considered a sustainable farming practice?
Alley cropping protects fragile soils through a network of roots produced by the trees and supplemental ground-cover resulting from fallen leaves and the companion crop. Rows of trees, shrubs, and/or grasses planted on the contour of a slope will also serve to reduce soil movement down the slope.
How does alley cropping prevent soil erosion?
What Is alley farming system?
Alley farming is an agroforestry system that involves the continuous cultivation of food crops between hedgerows of multipurpose trees on the same land. Woody legumes provide nitrogen-rich mulch and green manure to maintain soil fertility and enhance crop production, and protein-rich fodder for livestock.
What are the disadvantages of alley cropping?
One main disadvantage of the Alley cropping system is that additional labour is required to prune the trees. In general, the Alley cropping system advantages appear to outweigh the disadvantages. Farmers may also use Alley cropping to transition from one farming system to another system.
Why are rows and alleys important in cropping?
Rows and Alleys should be arranged to facilitate easy operation of the widest machinery to avoid damage to machinery and crops. Field Management – Alley cropping should be designed to optimize the use of light, water, and nutrients between woody plants and the inter-crops.

Tree rows (usually a mix of valuable hardwood species) established on cropland. Interstitial space between the trees is cropped with a range of species like cereals (for example, wheat, corn, and barley), oilseed, or protein crops (rapeseed, soya, fava beans, vetch, and peas, sunflower), vegetables, or vines.
