Sentences with phrase «organic yields»

The analysis we present here offers a new perspective, based on organic yield data collected from over 10,000 organic farmers representing nearly 800,000 hectares of organic farmland.

These hotspots were not associated with higher organic yields, but rather occurred in lower yielding regions for both conventional and organic production [39, 40].

The review paper describes cases where organic yields can be higher than conventional farming methods.

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.

While the proportion of soluble nutrient fractions is lower on organically managed soils, there is no decrease in organic yields since higher biological activity and higher mycorrhizal root colonization counteract nutrient deficiency.

On the other hand, Mäder et al. (2000) found no decrease in organic yields as an indicator for nutrient deficiency on farms which are managed organically for more than 30 years.

With respect to conservation interests, if more - efficient conventional farmers can match organic yields with 70 % of the land, remaining land could be set aside for conservation and other environmental benefits [9 — 12].

Averaged across all crops, organic yield averaged 80 % of conventional yield.

To establish organic agriculture as an important tool in sustainable food production, the factors limiting organic yields need to be more fully understood, alongside assessments of the many social, environmental and economic benefits of organic farming systems.

Seufert et al. present a meta - analysis of the available scientific literature on organic - to - conventional yield comparisons, and conclude that organic yields are indeed lower, but that the difference varies substantially according to crop type, growing conditions and management practices.

High yields came as a surprise: «There's been criticism that organic yields are lower than conventional yields,» Reganold says.

This study showed that with apples, organic yields can compare favorably with integrated and conventional systems.»

Based on our estimates, if all US wheat production were grown organically, an additional 12.4 million hectares (30.6 million acres) would be needed to match 2014 production levels in the U.S., unless the organic yield gap can be narrowed.

The opposite trend was observed for barley (Hordeum vulgare), wheat (Triticum aestevum), and hay crops, however, suggesting the geographical yield potential has an inconsistent effect on the organic yield gap.

For soybean (Glycine max) and potato (Solanum tuberosum), organic yield was more similar to conventional yield in states where conventional yield was greatest.

We took the farm tour and viewed large plots of land where the longest - ever side - by - side experiments have been conducted, comparing organic methods with non-organic, measuring yields, effects on soil, moisture, humus, microbiological activity, etc. (Initially, organic farming yields drop off, but within a few years, organic yields are equivalent of chemical farming yields, but in drought years, organic agriculture provides higher yields.
