Nš 1 "Custom-made" liquid fertilizers
In that technical specification you can find a general vision of the particularities of the process of fabrication of "custom-made" liquid fertilizers, as well as the main the main variables usually considered in the design of those products and mentioning specially the characteristics in which the needs of the farming for which they are developed result. All those questions are raised from a basically practical perspective, with the aim that the collected data can be illustrative for the Agronomical Technicians that think over the consideration of this kind of fertilizers in order to materialise their plans of fertilization.
Nš 2 "Chemical fundamentals for the estimate of the quantity of acid dosed in the automatic tightening of the pH in the nutritive solutions for fertirrigation"
An adequate control in fertirrigation needs the tightening between the pH and the concentration of nutrients in the dissolution of irrigation to previously fixed optimal values. The modern injection systems allow a good control of the contribution of nutrients, but the tightening of the final solution needs the addition of an acid, (usually a nitric one) whose dosage is automatic according to the signalled pH. In order to control totally the addition of fertilizers to the farming, it is necessary to make an estimate of the added quantity of acid. In that text we explain the chemical fundamentals to make a prevision of the quantity of acid automatically dosed in the supports for localized irrigation in the final tightening between the pH and the nutrients solution.
