Process for accelerating the rotting of straw and other harvest residues, and their incorporation in the organic soil matter, thereby simultaneously enhancing the activity of the soil

摘要

1. Method to accelerate the rotting of straw and other crop residues and also the incorporation thereof into the organic soil substance with simultaneous promotion of the soil activity through the use of slow-acting organically combined N-compounds in liquid phase, characterized in that an aqueous solution, able to be pumped, with a content of 10 to 80%-wt. dry matter and 20 to 90%-wt. water is applied on crop residues and, if required, distributed straw left on the arable soil, by spraying by means of output equipment as spray film or spray mist practically evenly distributed onto the arable soil and is worked in together into the topsoil by earth working equipment, or is applied only after the working in of the crop residues and, if required, of the distributed straw left on the ground and penetrates the rein, whereby the dry matter consists of 60 to 85%-wt. organic matter and 15 to 40%-wt. inorganic substances and the organic matter consists of 1.5 to 11.5%-wt. N in the form of slowly, constantly available organically combined N-compounds, in particular betaine, amino acids, such as glutamic acid as N-balance for the concentration of the broad C/N ratio of the supplied crop residues, particularly straw, to the C/N ratio of the soil substances of 10-12:1 through single or repeated application of the aqueous solution in the successive vegetation periods, and consists of 25 to 50%-wt. N-free, organic compounds as microbial C-and energy-source, preferably organic acids, polysaccharides, alcohols, ketones, carboxylic acids, starch, mono-, di-, oligo-saccharides, or derivatives of these substances, if required as mixtures, and also consists of 1.5 to 18.5%-wt. reducing sugars as glucose, and the inorganic matter consists of K-, Na-, Mg-, Ca- and P-compounds as water-soluble salts, such as sulphates, nitrates, or as organically combined ions, such as alginates, glutamates, salts of mono-carboxy-cellulose, particularly as KMgPO4 , hydrates thereof, or as KCaPO4 , K-silicate, K-carbonate, if required as a mixture of these substances, to accelerate rotting and to promote soil activity, and prior to application the aqueous solution is set to a high pH-value for physiologically acid arable soils or to a low pH-value for basically reactive arable soils.
