Our current agriculture system is extremely flawed in incredible and unstable ways. Sustainable agriculture is a journey rather than a destination; it aims to maintain ecosystems, support biodiversity, and meet the challenges of our fragile world. This article presents three severe issues, soil loss, dehydration, and food supply and examines possible solutions. So far, there is not a fully sustainable agriculture system, but the future shows great potential for improvement.

Soil is the key to life on earth; right soil is the most important factor for growing crops. Therefore, excavation is a major obstacle for farmers worldwide. Soil should be treated as a non-renewable resource; according to the USDA, Natural Resources Conservation Service, it takes at least 100 years to produce an inch of soil. During our lives the amount of soil has been rendered needless, many, many generations will not be changed. The tension removes the top and surface soil, which often have the highest biological activity and the highest amount of organic matter in the soil. This causes a decrease in nutrients and often creates a less conducive environment for plant growth. The plants need this soil for root development, to avoid explosion and for depth of root for spring, as well as water, air, and nutrients.

This problem is nothing new, and contains many ways to prevent further stress. The Soil Aggravator Act of 1935, the first national soil conservation program to respond to the biggest soil stress crisis, was the dust bowl. It established the USDA-NRCS, or the Natural Resources Conservation Service, a soil conservation service, to help farmers and runaways use their land protection techniques. These methods include conveyor powder, strip crop, trucking, as well as agriculture, shelter belt, crop rotation, and linoleum cover crops or remnants.

Due to unsafe irrigation, chicken, and boat practices, surface / rain water is not enough to meet our agricultural needs. In the 1950s, a major water resource problem was introduced in the introduction of electric pumps, which used ground water for irrigation. Prior to development, the groundwater system is in long-term equilibrium; the water removed is balanced with water, and the volume of water in storage remains relatively constant.

Although agriculture is unlikely to depend on irrigation, there are smart methods of irrigation and water conservation. When the soil is dry, a soil moisture tester can be used only to dry the fields to prevent water consumption and prevent water. Times, and morning / evening irrigation methods can be used to reduce dehydration, and minimal water use is essential. Methods to remove irrigation can be reduced by these methods and selecting better crops (grow less corn, less water wasted), to ensure which crops need irrigation (corn, and Other in-depth crops are not used for human consumption, but feed and ethanol for animals), and removes subsidies for crops using maximum water (high for high water consumption). Price). In addition, these crops have grown in crops that are not naturally in line with their growth. For example, the majority of all irrigated maize acreage in the United States is in four states: Nebraska, Kansas, Texas, and Colorado. These four states have different minorities and soil types. A change in the growing crops in the area where its needs may improve will naturally have little effect on irrigation practices.

Flood irrigation is one of the most popular methods of crop irrigation. Water is pumped or brought into the fields and the crops are allowed to flow with the land. This method is easy and inexpensive, and it is widely used by the community at least worldwide as well as in the United States. However, it is not effective or durable; almost half of the water used is not finished.

Waste water can be minimized from the surface of the fields; flood irrigation uses gravity to transport water, so water reaches mountainous areas and does not impede the field. At the surface of the field, water will be fully flowing throughout the water. This may be less due to flooding. Flooding is a less traditional type of irrigation. Generally, water is released only on a single field, but at the interval the water increases the flood rate, effectively reducing unwanted runoff. Finally, the run-off will increase the capture and reuse efficiency. A large amount of irrigation water is lost because it runs behind fields and banks. The water race can be captured in ponds and pumped back into the field, where it is used for the next cycle of irrigation.
