Wheat fertilization

Wheat

Wheat is one of the most cultivated cereals in the world and has a production yield that far exceeds that of other cereals considered lower than wheat. On the basis of the variety of wheat cultivated and produced, durum wheat and soft wheat are distinguished. Both are used in human nutrition and durum wheat contains more protein than soft wheat. From durum wheat semolina and semolina are produced, while flours are obtained from soft wheat. Wheat flours are used for bread making and for the production of pasta, sweets and biscuits. In particular, durum wheat is known and used for the preparation of pasta and bread. The main components of wheat flour are gluten, starch, dextrin, sugars, minerals, small amounts of fatty substances, vitamins, phosphates and coloring substances. Thanks to the new grinding techniques, the germ is separated from the caryopsis and, from it, a dark yellow oil is obtained which is used in the production of soaps. It must also be said that straw also comes from the cultivation of wheat. It is used to fill cattle bedding in stables, to make paper and to prepare bran.

Fertilization


The productive quality of the wheat is closely linked to the fertilizations, that is to the nutritional elements that are administered and which are indispensable for the growth of the cereal. Fertilization is a cultural practice that is of fundamental importance in plant cultivation. It is a delicate phase of their life cycle especially if the plant suffers negative effects on it that depend on climatic conditions or the bad conditions of the soil used for cultivation. Accurate and excellent fertilizations guarantee a good productive yield both qualitatively and quantitatively speaking. The essential elements in the cultivation of wheat are nitrogen, phosphorus and potassium, in some cases even sulfur. Nitrogen is the element par excellence that plays the most important role for the quality of wheat. A good producer should know these things and should be aware of the amounts of nutrients to be made. The quantities depend on some factors, namely the type of soil, fertility, climatic factors, planned interventions and other characteristics. The main rule that guarantees excellent wheat production is to supply nitrogen, phosphorus and, when necessary, potassium during the preparation of the soil or during sowing. the planned interventions and other characteristics.

Importance of nitrogen

Wheat needs the right nitrogen fertilization both in the pre-sowing phase and in the harvest phase.Fertilizing wheat with nitrogen-based fertilizers is not at all easy since it is not easy to establish the quantity of nitrogen that must be administered to the soil and the plant. The quantities to be administered depend on the type of soil used for cultivation and the climatic conditions in which the plant is to be grown. The ideal amount of nitrogen to be administered to the plant also varies according to the rainfall in that area. In fact, in rainy areas, most of the nitrogen is washed away and therefore is no longer absorbable by the roots of the plant. To avoid these problems, researchers and experts have “created” a fertilizer with a nitrification inhibitor. This allows to stabilize the nitrogen molecule ensuring the release to the plant before any type of chemical reaction that favors the formation of nitrates takes place. Through this procedure, the losses of nitrogen fertilizers are increasingly reduced.

Wheat fertilization: Fertilizers: which ones and how to use them

The fertilizers to be used are slow release or controlled release nitric, organic, ammonia and nitroammonia fertilizers. Nitric fertilizers are those that suffer the greatest losses, the organic ones are not always available and are the ones that last the longest, the ammoniacal ones are similar to the organic ones, the nitro ammoniacal ones are those that immediately lose part of the nitrogen. Slow-release or controlled-release fertilizers are those that are diluted in water and are released much slower than nitric nitrogen ones. The fertilization of the wheat takes place in three phases: from sowing to raising, from raising to flowering and from flowering to harvesting. In the first phase, the plant absorbs few nutrients including nitrogen. It must be carried out between the autumn and winter periods and a smaller quantity of nitrogen must be added. Nitrogen-based fertilizers must also be administered in the pre-sowing period but in very limited quantities. In case of rain the fertilization to be carried out is very different, half ammonia fertilizers and the other half nitric fertilizers should be administered. Nitric fertilizers must be administered after about a month from the rising period.
