Organic fertilizers in fruit orchards

A BioFruitNet practice abstract. Fertilization of organic fruit orchards strongly relies on authorized external commercial fertilizers leading to nutrient flows from conventional into organic farming systems. The use of alternative fertilizers including legume-based materials and non-contentious external commercial fertilizers, should be based on locally available resourced. An integrated approach is recommended.

Soil Health and Nutrient Density: Beyond Organic vs. Conventional Farming

Controversy has long surrounded the question of nutritional differences between crops grown organically or using now-conventional methods, with studies dating back to the 1940s showing that farming methods can affect the nutrient density of crops. More recent studies have shown how reliance on tillage and synthetic nitrogen fertilizers influence soil life, and thereby soil health, in ways that can reduce mineral micronutrient uptake by and phytochemical production in crops.
