How to Move Toward Sustainable Agriculture Practices

Since World War II ended, agriculture has dramatically changed. New technologies have caused food productivity to soar. Mechanization, specialization, and increased chemical use hinder farmers from producing lower-priced foods and fiber. Government policies that favor maximized production is a key factor.

 

These developments have many positive effects and reduce the risks associated with farming. But they also have significant costs. Topsoil depletion, air pollution, groundwater contamination, and greenhouse gas emissions only scratch the surface. Also, there is the decline of family farms, neglect of farm laborers' living conditions, and human health threats due to new pathogens. As well, rural communities are being disintegrated due to the concentration of economics in the agricultural and food industries.

 

Over the last four decades, a growing movement has come forth that questions the need for high costs. This movement offers more innovative and reasonable alternatives. This movement is toward sustainable agriculture. It continues to garner increasing acceptance and support in the food production sector. The three main goals of sustainable agriculture are social equity, environmental health, and economic profitability. Although the concept is made up of a wide range of practices, policies, and philosophies, there are a few common principles that define sustainable agriculture.

 

Throughout this movement, practice and science have led to many key farming techniques aimed at sustainability.

 

Crop Rotation and Diversity

 

Maintaining plant variety can be very beneficial. It results in improved pest control and healthier soil. Incorporating intercropping and complex crop rotations are ways of implementing crop diversity.

 

Irrigation

 

Rainwater can be collected or harvested with the use of gravity feed water tanks. Harvesting rainwater helps the environment and saves money. Water from wells, lakes, ponds, streams, rivers, and other sources can also be stored.

 

Cover Crops

 

Clover and hairy vetch are two types of cover crops. Cover crops are planted off-season when an area would be left bare. Planting cover crops allows the soil to be protected and builds soil health by replenishing nutrients, lowering the need to use herbicides, preventing erosion, and keeping weeds at bay.

 

Reduced or No-Till Methods

 

To prevent weed problems and to prepare fields for planting, traditional plowing known as tillage has been used. However, this generally causes massive soil loss. Reduced or no-till methods allow seeds to be directly inserted into undisturbed soil. This reduces erosion and improves soil health.

 

Overall, more diverse and complex agricultural practices have proven to be the most productive and sustainable.
