Romanian to English: The effect of nitrogen fertilization on the organic matter from General field: Science Detailed field: Biology (-tech,-chem,micro-)
Source text - Romanian Componenta cea mai importantă a materiei organice a solului este reprezentată de sistemul substanţelor humice.
Sistemul substanţelor humice joacă un rol deosebit în obţinerea recoltelor mari şi stabile în timp. El este supus permanent unui dublu proces: de humificare a materialului organic ce ajunge în sol şi de mineralizare a componentelor aflate în diferite stadii de humificare. Rezultanta acestui proces este influenţată de: tipul de sol, climă, irigaţie, fertilizare.
În această lucrare ne-am propus să studiem influenţa îngrăşămintelor chimice (NH4NO3) asupra materiei organice a solului. Am urmărit efectul acestor tratamente asupra aluviosolului molic de la Călăraşi.
Humusul reprezintă amestecul substanţelor organice amorfe aflate în sol şi se formează printr-un compex de procese biologice, biochimice, chimice şi fizice suferite de materia organică moartă, în special cea vegetală, iar microorganismele constituie factorul principal în desfăşurarea acestor procese.
Translation - English The main component of the soil organic matter is represented by the humic substances.
The humic substances system plays a special role in getting good and steady crops.He is permanently subject to a double process :of humification of the organic matter that ends up in the soil and of mineralization of the components in diffrent stages of humification.The result of this process is influenced by :soil type,clime, irrigation, fertilization.
In this paper we proposed to study the influence of the chemical fertilizers (NH4NO3) on the soil organic matter.We followed the eefect of these treatments on the alluvial mollisol from Calarasi.
The humus represents a mixture of amorphous organic substances found in the soil and si formed by a complex of biological,biochimical,chimical,and physical processes suffered by the dead organic matter ,especially the vegetal matter,and the microorganisms form the main factor in the display of these processes.
