Characterization of humified compounds by extraction and fractionation on solid polyvinylpyrrolidone
Biostimulant activity of two protein hydrolyzates in the growth and nitrogen metabolism of maize seedlings.
Two protein hydrolyzate–based fertilizers, one from alfalfa and one from meat flour, were studied chemically and biologically and a role of amino acids and small peptides of the two PHFs is suggested in the regulation of the hormone-like activity and nitrogen pathway.
Replant problems in South Tyrol: role of fungal pathogens and microbial population in conventional and organic apple orchards
There was a high level of organic matter in both the organic and the conventional apple orchards with no appreciable differences in humic fractions and most of the root-colonising pathogens belonged to the well-known root rot complex, Rhizoctonia solani and Pythium spp.
Determination of organic carbon in aqueous extracts of soils and fertilizers
Abstract A simple and accurate method for the routine determination of organic carbon in aqueous extracts of soils and fertilizers is described. Samples are oxidized for exactly 10 minutes with a…
