Agri-environmental indicator - mineral fertiliser consumption

In , In , 1. This article provides a fact sheet of the European Union EU agri-environmental indicator mineral fertiliser consumption. It consists of an overview of data, complemented by information needed to interpret these data.

The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer mineral or organic had significant effect in the nutritional status of the organic and conventionally managed mandarins. Nutrient uptake, vegetative growth, carbohydrate synthesis and soil characteristics were analyzed.

With the economy and farm finance more and more problematic, interest is growing in running farms with fewer, more accurate, and less expensive inputs and homemade fertilizers can help cut costs and keep fertility on the farm. By burning off carbon, we have created droughts even as ocean warming has sent more evaporation into the atmosphere. We have ignored that few things have more affinity for hydrogen than carbon, and if we want rain to adhere to and permeate our soils we need to build soil carbon. We thought salt fertilizers were cheap, and the stunning results encouraged us to wish away any hidden costs, no matter that earthworms disappeared simultaneously with the food chain that supported them. Our soils got hard and sticky as magnesium stayed behind while nitrates leached, carrying away silicon, calcium and trace minerals.

PhosAgro to build fertilizer production facility at Metachem site

Phosphorus is a macronutrient that plays a number of important roles in plants. It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result. It is also critical in biological energy transfer processes that are vital for life and growth. Adequate phosphorus results in higher grain production, improved crop quality, greater stalk strength, increased root growth, and earlier crop maturity. For over one hundred years, phosphorus has been applied to crops as fertilizer—first as ground bone and now as some chemical reaction product of ground rock. Yet, for all that experience, its management cannot be taken for granted. Phosphorus is not lost into the atmosphere—rarely does it leach beyond the reach of roots—and its availability to crops can be accurately estimated by soil testing. The challenge is that phosphorus is a macronutrient in plants but behaves somewhat like a micronutrient in soils. The concentration of soluble phosphate in the soil solution is very low, and phosphorus is relatively immobile in the soil.

All plants take up nutrients from the soil as they grow; these nutrients are removed with any plant that is harvested.

Organic growers frequently attempt to quantify the amount of organic nitrogen they add to their soil ecosystems in the same manner that conventional growers use inorganic nitrogen units to calculate their nitrogen requirements. Logically, they reason that a ton of organic material with 4 percent nitrogen content as verified by a laboratory test will provide 80 pounds, or units by some determinations, of nitrogen. The truth is that organic nitrogen sources vary in their efficiency of transformation into soil components over a much broader range of response than do inorganic synthetics, which offer precision measurement and a repeatable predictability of release.

Fertilizer is a substance added to soil to improve plants' growth and yield. First used by ancient farmers, fertilizer technology developed significantly as the chemical needs of growing plants were discovered. Modern synthetic fertilizers are composed mainly of nitrogen, phosphorous, and potassium compounds with secondary nutrients added. The use of synthetic fertilizers has significantly improved the quality and quantity of the food available today, although their long-term use is debated by environmentalists. Like all living organisms, plants are made up of cells. Within these cells occur numerous metabolic chemical reactions that are responsible for growth and reproduction.

Soil fertility

A fertilizer American English or fertiliser British English ; see spelling differences is any material of natural or synthetic origin other than liming materials that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Many sources of fertilizer exist, both natural and industrially produced. Management of soil fertility has been the preoccupation of farmers for thousands of years. Egyptians, Romans, Babylonians, and early Germans are all recorded as using minerals and or manure to enhance the productivity of their farms. John Bennet Lawes , an English entrepreneur , began to experiment on the effects of various manures on plants growing in pots in , and a year or two later the experiments were extended to crops in the field. One immediate consequence was that in he patented a manure formed by treating phosphates with sulfuric acid, and thus was the first to create the artificial manure industry. In the succeeding year he enlisted the services of Joseph Henry Gilbert , with whom he carried on for more than half a century on experiments in raising crops at the Institute of Arable Crops Research. The Birkeland—Eyde process was one of the competing industrial processes in the beginning of nitrogen based fertilizer production.

Homemade Fertilizers

Soil fertility refers to the ability of soil to sustain agricultural plant growth , i. In lands used for agriculture and other human activities, maintenance of soil fertility typically requires the use of soil conservation practices. This is because soil erosion and other forms of soil degradation generally result in a decline in quality with respect to one or more of the aspects indicated above.

How to Convert an Inorganic Fertilizer Recommendation to an Organic One

Successful production of any crop begins with the soil. A fertile, biologically active soil provides plants with most of the nutrients needed for good growth. Fertilizers can supplement or renew these nutrients, but they should be added only when a soil test indicates the levels of available nutrients in the soil are inadequate for proper plant growth and high yields. Whether you are growing annuals or perennials, vegetables or flowers, most crops have a few short months to grow and develop flowers and fruits.

The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer mineral or organic had significant effect in the nutritional status of the organic and conventionally managed mandarins.

Livestock production is important for food security, nutrition, and landscape maintenance, but it is associated with several environmental impacts. To assess the risk and benefits arising from livestock production, transparent and robust indicators are required, such as those offered by life cycle assessment. A central question in such approaches is how environmental burden is allocated to livestock products and to manure that is re-used for agricultural production. To incentivize sustainable use of manure, it should be considered as a co-product as long as it is not disposed of, or wasted, or applied in excess of crop nutrient needs, in which case it should be treated as a waste. This paper proposes a theoretical approach to define nutrient requirements based on nutrient response curves to economic and physical optima and a pragmatic approach based on crop nutrient yield adjusted for nutrient losses to atmosphere and water.

Nitrogen: Organic vs. Synthetic

This NebGuide discusses the availability and use of manure nutrients for field crop production. When managed correctly, nutrients in livestock manure can be a valuable resource. When managed improperly, however, these same nutrients represent a potential environmental pollutant. Accurate crediting of manure nutrients within a total crop nutrient program is fundamental to utilizing manure as a resource. This NebGuide illustrates how to estimate the crop available manure nutrients part c, Figure 1 and calculate an agronomically based manure application rate. There are other tools available that do the calculations for you.
