What are the environmental effects of water waste?

Water waste can lead to soil erosion, overwatered crops, and unnecessary spend.

How to improve soil quality?

Follow Best Practices for Better Soil Quality. By focusing on better soil quality, your soil can better hold moisture and oxygen for plants to thrive. This will cut down on the amount of water needed on a regular basis. Good soil management practices include fertilizing with manure, adding compost, and reducing tillage frequency.

What are the best ways to grow crops?

All crops you grow need to be ideal for your climate. If plants are native to your region, they will be more likely to succeed in natural weather conditions, such as periods of drought. In addition, if your region usually experiences periods of drought, consider planting crops that are acclimated to periods without enough water. This can help cut down on watering.

Why do farmers rotate their crops?

Many farmers rotate the types of crops they plant by season or year, thus providing enough variety for the soil and plants to thrive. Different crops need different soil nutrients and water amounts. By constantly rotating the types of crops, there’s usually a higher crop yield.

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?

Another good technique to favor water saving, still aiming to maintain the soil covered, is to insert into the productive circle, the so-called cover crops; in this way the soil will not stay bare between the crops periods.

Why is conservative minimum tillage more efficient?

In this case, conservative minimum tillage techniques are more efficient, because they let the soil settled. Also, the presence of crop residues on the soil surface helps to reduce the evapotranspiration and, in case of heavy rains, the water flow on the surface; the water flows slowly, it gains time to penetrate in the soil.

Why is organic matter important?

The organic substance improves the hydro capacity of the fields and the water infiltration as well. Thanks to its hydrate capacity, and most important, thanks to the binding action of the soil particles, offers more stable agglomerates, preserving the soil porosity.
