How does drip irrigation work?

Drip irrigation systems deliver water directly to a plant’s roots, reducing the evaporation that happens with spray watering systems. Timers can be used to schedule watering for the cooler parts of the day, further reducing water loss.

Why do we need cover crops?

Planted to protect soil that would otherwise go bare, cover crops reduce weeds, increase soil fertility and organic matter, and help prevent erosion and compaction. This allows water to more easily penetrate the soil and improves its water-holding capacity. A 2012 survey of 750 farmers conducted by North Central Sustainable Agriculture Research and Education found that fields planted with cover crops were 11 to 14 percent more productive than conventional fields during years of drought. Woodleaf Farm uses perennial grass and clover in their peach orchards, and at Frog Hollow Farm, organic fruit farmer Al Courchesne swears by his use of cover crops for building healthy soil.

What is smart water management?

Smart water management is not just about how water is delivered but also when, how often, and how much. To avoid under- or overwatering their crops, farmers carefully monitor the weather forecast, as well as soil and plant moisture, and adapt their irrigation schedule to the current conditions.

Why are crops grown in arid regions?

Crop species that are native to arid regions are naturally drought-tolerant, while other crop varieties have been selected over time for their low water needs.

Why is soil moisture important?

According to the two companies, soil moisture data is becoming a key component of global sustainable farming programs, as producers contend with increasingly erratic weather patterns and drier growing seasons. Measuring precise moisture conditions in their fields can help farmers maintain soil health, improve water conservation, and increase crop yield.
