How to favor water saving?

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.

What is the most efficient irrigation system?

The most efficient irrigation systems are the ones able to distribute the water in very precise points (85-90%), that means in proximity of the plant, near to soil or directly into it. In this way there is a saving of time in terms of water exposition to the air and water flowing from the pipe to the roots.

Why is mulching important?

Mulching using plant-based material or biodegradable films, plays an important role in the water saving scenario.

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?

Water risk is an often-overlooked topic for most people on a daily basis, but the agricultural industry is becoming more and more aware of the issues at hand. It serves high importance to agriculture as it can affect groundwater supply. Water risk is the main component of water management and can affect the agriculture business.

Groundwater trading

It is common for landowners in western states to trade groundwater. The focus is more on the supply-side approach or importing surface water and the demand-side approach of the exchange and trading of groundwater, rather than water management.

Overcoming challenges

Finding out to conserve water after understanding what water stress is and its components, the challenge is now finding out how to incentivize companies to conserve their water supply. For Western states, specifically, California, the demand and supply of water for agricultural use lessens the need for proper water management.


As people of the 21 st century, we have been told to use less water due to a water shortage. This suggestion is often taken lightly because even with the warnings, the tap never stops running.

Project Description and Results

Dr. Sandoval from UC Davis was approached by PVWMA to aid them in their agricultural conservation program. PVWMA wanted to know the volume water that could be potentially saved and the resulting economic impact of water savings on the valley. The key to agricultural water savings is to water a crop to its evapotranspiration (ET) value.

Economic Impact

This increase in water savings results in a direct decrease in revenue for PVWMA ranging from $862,000 to $951,000. To compensate for this loss in revenue, a potential increase in water extraction fee rates was analyzed.
