The results indicated that during the incubation periode the application of phosphorus fertilizer increased the contents of Ca2-P and Ca8-P significantly,but had little effect on those of A1-P,Fe-P and O-P.

Regression coefficients showed a possible source of POC in water-stable aggregates from increased crop biomass in topsoil(0-5cm) and organic matter applied in sub-surface layer(5-15cm).

As an application we produce complete hyperbolic 5-manifolds that are nontrivial plane bundles over closed hyperbolic 3-manifolds and conformally flat 4-manifolds that are nontrivial circle bundles over closed hyperbolic 3-manifolds.

As an application of the results we prove a generalization of Chevalley's restriction theorem for the classical Lie algebras.

The proof is an application of a recent result by W.

The application arises because of a very strong homological property enjoyed by certain cell filtrations forq-permutation modules.

We give as an application a family of singular Schubert varieties.

Using the properties ofn-Hopf algebras we show that certain spaces do not admit the structure of ann-valued group and that certain commutativen-valued groups do not arise by applying then-coset construction to any commutative group.

A basis is calledmonomial if each of its elements is the result of applying to a (fixed) highest weight vector a monomial in the Chevalley basis elementsYα, α a simple root, in the opposite Borel subalgebra.

Our lower bound comes from applying a decomposition theorem for "hyperbolic localization" [Br] to this torus action.

We then clarify the results by applying the theory of von Neumann algebras.

We present here a self-contained derivation, building the decomposition from basic principles such as the Euclidean algorithm, with a focus on applying it to wavelet filtering.

The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.

These results are applied to the theory ofcompactly causal symmetric spaces: we describe explicitly the complex domain Ξ associated to such a space.

This paper shows how the Kazhdan-Lusztig theory of cells can be directly applied to establish the quasi-heredity ofq-Schur algebras.

In [Ka1] its geometric counterpart was applied to construct contractible smooth affine varieties non-isomorphic to Euclidean spaces.

In the final section the theorem is applied to gradient actions on other homogeneous spaces and we show, that Hilgert's Convexity Theorem for moment maps can be derived from the results.

Effects of solid water and foliar fertilizer on survival and growth of seedlings in sand prevention and control

To promote afforestation in sandy lands and increase the effects of prevention and control of desertification, the application of a new drought-resistant product-solid water and foliar fertilizer "Shifengle"-was studied.

A comparison of three treatments (solid water, foliar fertilizer, and control) showed that both solid water and foliar fertilizer increased plant survival rate by 10% and 18.2%, respectively.

Ltd had a higher carbon conversion of 3%, a lower specific oxygen consumption of about 8%, and a lower specific carbon consumption of 2%-3% than that of Texaco CWS gasification at the Lunan Fertilizer Plant.

The results show that fertilizer and soil are important factors determining the aerosol particle over agricultural fields, and vegetable fields in suburban Beijing contribute significantly to the aerosol particle.

The present paper reports studies on the relative rate of decomposition of nine different oil cake-meals [soybean, peanut, sesame, rape seed, cotton seed(with and without hull), chinese tallow seed (with and without hull)]. In the course of decomposition of the different oil cake-meals, freguent measurement were made of the quantity of evolved CO_2 gas, and amount of the NH_4~+, NO_3~-, and NO_2~- nitrogen formed at the given intervals of the day. These measurement served as indices of the intensity of decomposition...

The present paper reports studies on the relative rate of decomposition of nine different oil cake-meals [soybean, peanut, sesame, rape seed, cotton seed(with and without hull), chinese tallow seed (with and without hull)]. In the course of decomposition of the different oil cake-meals, freguent measurement were made of the quantity of evolved CO_2 gas, and amount of the NH_4~+, NO_3~-, and NO_2~- nitrogen formed at the given intervals of the day. These measurement served as indices of the intensity of decomposition and rate of ammonification and nitrification of the oil cake-meals that may be occur in the soil. These studies were performed in the laboratory, under room temperature condition of the summer season. All cakes were ground into meals to such particle size as to pass through a 20-mesh sieve. The cake-meals were separately mixed with cultivation soil in the proportion of one part of cake-meal to hundred parts by weight of soil. The soil used was of alluvial origin, low in organic matter and somewhat sandy in texture. It was found that decomposition of the cake-meals began soon after their application to the soil. The daily evolution of CO_2 reached its maximum for about one week. Immediately after that, the daily evolution of CO_2 declined rapidly to a such lower level and attained a rather steady declining rate after about two weeks. The trends were common in character irrespective of the kind of the cake-meals. Among the organic constituents of tile cake-meals that underwent into decomposition in the early days, nitrogeneous organic compou ads seemed to be of major importance. The production of ammonium compounds as a result of ammonification followed a trend similar to that shown by the evolution of CO_2. The maximum rate of ammonification was noticed sometime before the evolution of Co_2 had reached a maximum. The positive correlation existing between the total nitrogen content of the oil cakes and the rate of ammonification was evident. Other factors, however seemed to be also affecting the status of transformation of Nitrogen compounds. Nitrate compounds began to appear soon after ammonification had proceeded to an appreciable degree. In the course of decomposition their accumulation in the soil increased steadily with the time. Small amounts of nitrites were found under the experiment conditions which were characterized by low moisture content (25%) of the soil and meal mixtures. From the quantity of the total available nitrogen accumulated at different intervals in the course of decomposition as in the case here given, it seemed that some nitrogen might be lost through volatilization of ammonium compounds, since the soil was alkaline in reaction (the soil here used had a PH value of 7.2) Soaking the cake meals with water, lime-water, or straw-ash extract as sometimes practiced by the local farmers in some districts in Chekiang province brought about the effect of hastening ammonification and nitrification processes. But, gain in readiness of availability of the meals by this hastening effect might not compensate for the loss in total amount of available nitrogen formed. The loss was particularly evident when the cake-meals were pretreated with lime-water or straw-ash extract. It is believed that the alkaline reaction of the treated cake-meals accounts for this loss. The relative readiness of decomposition of the different oil cake-meals followed in descending order: soybean, sesame, peanut, Cotton seed (without hulls)>Cotton seed (with hulls), rape seed>Chinese tallow seed (with and without bulls). Similarly, the relative total amount of available nitrogen (including ammonium and nitrate nitrogen) formed during decomposition shows in the following order: soybean, peanut, sesame, chiness tallow seed(without hulls)>Cotton seed (with and without hulls)>rape seeds>Chiness tallow seed (with hlls).
