Field experiments were conducted from 2011–2013 at three different sites, including Honghu, Shayang, and Jingzhou in China, to determine the effects of fertilization on enhancing crop productivity and indigenous nutrient-supplying capacity (INu S) in a rice (Oryza sativa L.)-rapeseed (Brassica napus L.) rotation.

Four mineral fertilizer treatments (NPK, NP, NK and PK) were applied in a randomized complete block design with three replicates.

Fertilizers or fertilisers are compounds given to plants with the intention of promoting growth; they are usually applied either via the soil, for uptake by plant roots, or by foliar spraying, for uptake through leaves.

New research helps explain how iron in the soil may unlock naturally occurring phosphorus bound in organic matter, which can be used in fertilizer, so that one day farmers may be able to reduce the ...

On a larger and more relevant scale, manure runoff can and does cause algae blooms and can make water unfit to drink.

Production of rock fertilizers — gypsum, greensand, lime and the rest — involves mining and milling, which in turn require fossil fuels.Without the beneficial effects of worms and micro-organisms, plants have a harder time accessing the secondary and micro-nutrients not found in most chemical fertilizers.Chemical fertilizers can be equally hard on plants themselves, because they bypass the work a plant normally has to do to gain access to nutrients.However, the ecological damage done by producing organics, either at present or potentially, does not approach that done by synthetics.Incredible accomplishments have been achieved in agricultural production in China, but many demanding challenges for ensuring food security and environmental sustainability remain.The three chemicals that qualify as secondary nutrients, calcium, sulfur, and magnesium are generally ignored, as are the trace nutrients, boron, chlorine, manganese, iron, zinc, copper, and molybdenum.While these are needed in far smaller quantities than the macro-nutrients, they are still essential.But new evidence, gleaned from antlers obtained in late 1990 or early 1991, shows that it survived for at least an ... They occur in places wherever plants are abundant -- such as the raging fires currently burning in the Brazilian Amazon. Feeding the world's growing population is one of the great challenges of the 21st century, particularly in China, which has nearly a quarter of the world's population but a fraction of the cropland. Researchers have developed a new platinum-based catalytic system that is far more durable than traditional commercial systems and has a potentially longer lifespan. There are several organic fertilizer benefits, some purely altruistic, others much more self-interested. After all, nitrogen, phosphorus, and potassium ARE chemicals, so where is the advantage in these bags of heavy, grainy stuff, that need to be measured and mixed and then dug in, when you can just pick up a small plastic bottle of the blue stuff?
