    1. Diagnosing Crop Nutrient Deficiencies in the Field

      This article is from ECHO Asia Note #29 The old adage ‘You can’t fix a problem if you don’t know you have one’ underpins the basic science of diagnosing plant nutrient deficiencies. For years, farmers and scientists have worked together to identify a set of visual clues that can be used to...

    4. Improving intercropping: a synthesis of research in agronomy, plant physiology and ecology

      Abstract, 2014, New Phytologist Trust Intercropping is a farming practice involving two or more crop species, or genotypes, growing together and coexisting for a time. On the fringes of modern intensive agriculture, intercropping is important in many subsistence or low‐input/resource‐limited...
