Full textThe aim of the study was to identify and characterize natural raw materials as a potential soil improver. The capacity for measurable influence on the chemical, physical and biological properties of sandy substratum was investigated. The differentiated affect of the raw materials has been tested for maize and wheat using test series in a greenhouse as well as in open fields. Raw wool, sheep wool pellets and spent grains were considered based on comprehensive literature research. It was observed that spent grains can provide large amounts of nitrogen (N=3.95\%; C/N=12.74). Moreover, it contains relatively high levels of phosphorus and magnesium (8.68 g kg-1 and 4.05 g/kg, respectively), but only small amounts of potassium (1.40 g/kg). Furthermore, a short-term improvement of the water storage capacity of sandy substratum using a application rate of 0.5 M.-\% was observed. Raw wool has higher amounts of nitrogen with Nt=13.56\% compared to spent grains. Moreover, higher levels of potassium with a value of 35.41 g/kg were observed, but spent grains have lower levels of magnesia and phosphor with values of 0.23 g/kg and 0.34 g/kg, respectively. The mineralization of the raw wool occurs slowly compared to (malt) spent grains, such that nutrients are slowly available to plants. Initially, raw wool has a highly hydrophobic character with increasing depletion of Lanolin a measurable improvement of the water storage capacity of sandy substratum using an application rate of 0.1 M.-\% was observed. Nutrients available to plants are provided quicker by industrially remanufactured sheep wool pellets in comparison to raw wool. Nutrients are released on a long-term basis by sheep wool pellets similar to the raw wool and the influence on the soil-physical properties are verifiable for longer periods of time. However, an application rate of 0.5 M.-\% is necessary.

Full textSoil degradation leading to a lack of humus, nutrients and water especially on exploited sites causes the worldwide need in soil amendments. Aim of the work was the development of hydrogels from renewable biopolymers starch and lignin improving water retention especially in degraded soils. A significant increase of hydrophilic properties of starch was obtained by chemical modification with the objective of forming starch based hydrogels. Swellable hydrogels were formed by cross-linking of water soluble starch derivatives like carboxymethyl starch and monostarch monophosphates with di- and tricarboxylic acids. Swelling capacity and rheological properties of the starch gels were selective adjusted by variation of cross linking agent and whose amounts. Modification of lignin was realized by oxidation with hydrogen peroxide partly in combination with ferrous and manganese chlorides, respectively. In consequence of oxidative structural changes which were cleavage and oxidation of side chain as well as aliphatic and aromatic hydroxylation, gelation of lignin was improved significant. Lignin hydrogels with different swelling capacities and rheological functions were formed by cross-linking lignin with different amounts of poly (ethylene glycol) diglycidyl ether. Application of hydrogels based on starch and lignin causes increased water storing capacity/field capacity and decreased evaporation of a sandy soil as well as an increased biomass yield of yellow mustard (Sinapis alba)

Full textThe development of a novel artificial humus material at the Institute of Wood- and Plant Chemistry was accounted by the increasing demand for high grade humic matter. This N-modified product base on a patented ambient pressure technology of the oxidative ammonolysis. of lignin containing substances, in particular Lusitian lignite. Objective of the work was to broadening the current knowledge of structural properties with focus on the contents and characteristics of humic substances fractions (humins, humic acids, fulvic acids). Especially attention was given to nitrogen and its way of incorporation into organic matter. For isolating humic substances the IHSS method was used. The procedure was adapted in order to increase the yield of humic acids and decrease time needed. Main characteristics of N-modified substances are higher contents of humic acids and subtly differenciateted effective N-binding forms with leads to higher diversity of the chemical functionality. This and the low ash content makes the differences to other brown coal based soil improving agents available on the marked. It has been shown that humic acids give the main part providing nitrogen and functionality (e.g. cation exchange capacity). The oxidative ammonolysis leads to regenerated humic acids as well as e.g. the clevage of aromatic structures by reactions of free phenolic groups. In contrast to former assumptions the cleavage is not strongly related to demethoxylation or strong reaction conditions like high pressure. This and other reactions lead to short, middle, and long lasting N-binding forms. 15N-NMR-spectroscopic investigations on a 15N-enriched product, Py-GC/MS-investigations and conventional investigations show an overestimation of heterocyclic, in particular heteroaromatic N-binding forms up to now. Consequently amide like nitrogen reveals as extraordinary according to its persistent behaviour to hydrolysis and plant availability respectively. Corresponding the correlation of the N-incorporation and humic acid content of raw materials the latter can be used for evaluating possible raw material for its usage for N-modification. It can be easy obtained in a degratadive way. From the process engineering point of view the success of N-incorporating is strongly correlated to the oxidation conditions during processing. Using pure oxygen instead of air shorts the needed reaction at 50%
