Policies to promote environmentally sustainable fertilizer use and supply to 2020 by Bumb, Balu L., Baanante, Carlos A.

“…In the mid-1960s, when projections of global starvation were common, no one questioned the role of mineral fertilizer (plant nutrients, mainly nitrogen, phosphorus, and potassium from inorganic sources) in promoting food production in the food-deficit countries. …”

Reduction of potassium fixation by 2 humic-acid fractions in vermiculitic soils by Olk, D.C., Cassman, K.G.

“…An increase in extractable and highly labile K occurred within 4 h of MHA addition and thus appears to result from a rapid exchange reaction and not from mineral dissolution; the latter was confirmed in separate experiments with organic acids. …”

Effects of earthworms on soil properties and rice production in the rainfed paddy fields of Northeast Thailand by Choosai, C., Jouquet, Pascal, Hanboonsong, Y., Hartmann, Christian

“…Casts appeared as patches of fertility with more fine particle sizes and organic matter contents, a higher CEC, as well as a much higher concentrations of mineral elements (N, P and K). As a consequence, our results suggest that earthworm activity lead to a significant higher rice yield. …”

Aluminium stress in crop plants by García Oliveira, A.L., Chander, S., Barcelo, J., Poschenrieder, Charlotte

“…Aluminium (Al) toxicity has a strong negative impact on crop productivity on acid mineral soils. Liming and fertilisation frequently are insufficient to overcome the problem, especially in tropical areas with subsoil acidity. …”

Edaphic and climatic factors that affect intake and selectivity of forage plants under grazing by Lascano Aguilar, Carlos Eduardo

“…Some of the papers reviewed associate this effect with the correction of mineral deficiencies, with changes in plant growth and morphology, and with the reduction of certain chemical components such as tannins. …”

Iron and zinc concentration of native Andean potato cultivars from a human nutrition perspective by Burgos, Gabriela, Amoros, Walter, Morote Quispe, Maximo, Stangoulis, James, Bonierbale, Merideth

“…The determination of iron (Fe) and zinc (Zn) concentrations in 49 native Andean potato varieties revealed significant genotypic variation. Comparison of mineral concentrations of 37 of these germplasm accessions grown in two highland locations further revealed significant variation due to environments and genotype × environment interaction. …”

Utilización de medición de sólidos solubles totales como aproximación al contenido de steviolglicósidos en stevia rebaudiana by Taiariol, Dario, Leiva, Nelson Jose

“…Estos contenidos dependen en gran medida, del genotipo y las condiciones ambientales, del manejo de prácticas agronómicas, como la nutrición mineral y el riego. El objetivo de este trabajo fue observar la variación estacional de Steviolglicósidos en cuatro genotipos y su correlación con un método sencillo de medición por ºBrix, de los mismos.…”

Respuesta del hinojo en cultivo ecológico by Pomares, Fernando, Baixauli, Carlos, Aguilar, José M., Canet, Rodolfo

“…Ahora bien, mientras en el cultivo intensivo o convencional se infravalora la importancia de la calidad del suelo como factor productivo, practicándose en muchos casos una fertilización exclusivamente mineral, en los sistemas de producción ecológica se considera que una buena fertilidad del suelo es el requisito fundamental para lograr cultivos productivos, equilibrados, que proporcionen cosechas de elevada calidad nutritiva y sanitaria.…”

Propiedades de los suelos by León Moreno, Clara

“…La desintegración de las rocas en partículas más pequeñas, junto con el aporte de materia orgánica por parte de plantas y animales, dieron comienzo al suelo; el suelo está compuesto de una parte mineral (partículas de rocas), de otra orgánica (restos de hojas, excrementos, etc.) que se descompone gracias a la presencia de organismos como lombrices y microorganismos, y de agua y aire, esenciales para que se pueda dar lo anterior.…”
