At Clif Bar, the company is tackling the yield gap by investing in plant breeding, contributing to an agriculture fund that helps provide technical assistance to educate growers and investing in infrastructure that will help reduce the distance that organic producers must transport their crops from the farm gate to the aggregator or processor, which is a significantly longer distance than for most conventional producers, Dillion said.
He added that many US crops transitioning to organic have a yield drag of about 30 - 40 % below conventional crop yields, which «is not really acceptable to farmers long - term when you look at their economics.»
But the study went a step further, comparing crop yields on conventional farms to those on organic farms where cover crops were planted and crops were rotated to build soil health.
Because organic agriculture produces on average only half the yield of crops per unit of land as conventional farming, any mass conversion to organic would end up using much more land.

While organic agriculture practices result in higher soil organic matter (SOM) contents and, in turn, higher nutrient - and water - supplying potential to crops, transition to organic farming typically involves a lag time of several years in which yields can suffer and input demands increase as rebuilding soil microbial communities compete with crops for nitrogen and other available nutrients (Simmons and Coleman, 2008).
Savage's methodology couldn't have been simpler: He lined up and charted organic and conventional yield data for the same crop and state in which they were harvested.
The USDA / NASS studies tracked harvested acres without differentiating between irrigated and non-irrigated acreage; it gathered data on planted vs. harvested acres for some crops but not others; it did not account for systems in which «baby vegetable» crops (usually organic) are grown in short rotations on the same plot (such as spinach, lettuce, and carrots) and thus have lower yields; and it omitted some data that would have revealed too much information about individual farmers, in cases where very few growers produce a particular crop.
Rodale Institute's Research Department investigates a number of scientific and regenerative farming issues, including cover crop practices, organic weed management, organic no - till systems, compost use, influences of agricultural practices on water quality, and effects of mycorrhizae and other soil biota on crop and soil health, and yields.

However, several crops had no significant difference in yields between organic and conventional production, and organic yields surpassed conventional yields for some hay crops.
Insect and disease damaged fruits and vegetables can quickly become unmarketable, and this might explain the relatively low organic yields of fruit and vegetable crops compared to their conventional counterparts.
The organic to conventional yield ratio varied widely among crops, and in some cases, among locations within a crop.
Averaged across all crops, organic yield averaged 80 % of conventional yield.
Even so, a dramatic, sustained reduction in crop yield could be devastating to food security, even in developed countries, making a rapid and complete switch to organic agriculture unwise.
