- Farming with rocks and minerals: challenges and opportunities Peter Van Straaten Multidisciplinaria (Ciencias Naturales y Exactas) phosphate rock rock fertilizer soil nutrient replenishment In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capitafood production is the declining quality and quantity of soils. To reverse this trend and increase soil fertilitysoil and plant nutrients have to be replenished. This review provides a literature survey of experiences ofusing multi-nutrient rock fertilizers for soil fertility enhancement from temperate and tropical environments.Advantages and limitations of the application of rock fertilizers are discussed. Examples are provided fromtwo successful nutrient replenishment projects in Africa where locally available rock fertilizers are used onhighly leached acid soils. The potential of combining organic materials alongside rock fertilizers in soilfertility replenishment strategies is stressed. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778409 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.78
