How does conservation tillage work?
Conservation tillage is a way to reduce the amounts of sediment and nutrients that move into water from agricultural lands. Two types of conservation tillage are minimum tillage and no-tillage. Minimum till leaves at least 30 percent of the soil surface covered with plant residue after the tillage or planting operation. No-tillage is the practice of leaving the soil undisturbed from harvest to planting, except for nutrient injection. Crop seeds are planted by a device that opens a trench or slot through the sod or pervious crop residue. Conservation tillage can reduce soil loss by 50 percent or more as compared to conventional tillage.
Why are agricultural BMPs important?
Using agricultural BMPs can help to prevent or minimize the effects of nonpoint source pollution. Most agricultural BMPs help to control sediment carried off of agricultural lands, encourage sound pest and nutrient management techniques, and prevent or minimize potential runoff to ensure economic, environmental, and agronomic sustainability.
Why is nutrient management cost effective?
Nutrient management is cost-effective because it limits the amounts of nutrients lost. Furthermore, it is one of the best ways to reduce nonpoint source nutrient pollution. Vegetation in riparian buffers and healthy pasture systems help to filter out nutrients before runoff reaches surface waters.
Why is it important to use irrigation water management?
Applying too much water increases pumping costs, reduces water efficiency, and increases the potential for nitrates (NO3) and pesticides to leach into groundwater. On the other hand, delaying irrigation until plants are water-stressed can reduce yield and make fertilizers and pesticides less effective. An irrigation water management plan should use soil-moisture monitoring techniques to determine when irrigation is necessary. Irrigating only when a crop needs it is an effective BMP for reducing nonpoint source pollutants.
What is a nonstructural practice?
Nonstructural practices, on the other hand, are activities or behaviors that reflect better planning and management and increased education and awareness. …
How can vegetation help fish habitat?
Mature, woody vegetation along stream-banks can lower stream temperature and improve fish habitat. There are many government programs to help farmers and ranchers design and pay for agricultural BMPs to control nonpoint source pollution.
What is IPM pest control?

How does regenerative agriculture help the environment?
By focussing primarily on soil health rather than the seeds that are sewn , regenerative agriculture promotes a system where the “health of soil, plants, animals, and humans is one and indivisible”. 12 This more circular and holistic view of production is also thought to help crops and fields become more resilient during stressful conditions – particularly during droughts. 13
How can digitalization help farmers?
Some companies are now able to empower farmers to make data-driven decisions and reduce their water consumption by up to 30% thanks to soil-moisture sensors. 6 The Italian company Bluetentacles allows farmers to irrigate fields only when it’s necessary, thanks to climate and soil moisture data. A similar system has also been developed by the Spanish startup BioAgro, which has created a smart irrigation platform using low-cost technology based on information obtained by sensors. The sensors calibrate soil moisture and allow automatic irrigation and application of fertilisers only when the crops need it. These platforms could also provide farmers with forecasting and alerts about conditions that may threaten crops, so they can take appropriate action in a convenient and timely way.
Why is it important to store water in a smart way?
In Colombia, the CGIAR Research Programme on Climate Change, Agriculture and Food Security (CCAFS) focuses on climate-smart agriculture (CSA) to help small-scale farmers adapt to and mitigate the effects of climate change . This is achieved by catching rainwater when it’s available and helping farmers to efficiently channel rainwater to reservoirs or storage tanks to be used when the weather is drier. 9
