The application of organic fertiliser is a commonly used method to improve the utilisation efficiency of phosphorus (P) fertiliser. However, long-term over-fertilisation will cause environmental pollution. This study analysed a field test was conducted to study the impacts of P forms in soil under long-term (40 years) rotation fertilisation, to evaluate the contribution of different fertilisation to the available P form, to clarify how to apply pig manure to improve the concentration of available P forms. The results show that the main P compounds were orthophosphate and phosphate monoester. The combination of a high amount of manure and NPK fertilisers...

A field experiment lasting 37 years was conducted to evaluate the applications of different rates of pig manure and mineral fertilisers alone or in combination impacts on total phosphorus (Ptotal) and Olsen phosphorus (POlsen) contents and phosphorus activity coefficient (PAC, percentage of POlsen to Ptotal) within soil water-stable aggregates (WSA) in a Mollisol of Northeast China. The contents of Ptotal...

The aim of this study carried out in 2017-2018 was to determine the effect of white cabbage (Brassica oleracea L.), which is known to have an allelopathic effect on the germination of some weed and cultural crops seeds. In addition to weeds, Amaranthus retroflexus L., Chenopodium album L. and Solanum nigrum L., cultural plants such as Zea mays L., Beta vulgaris L., were used in this study. It has been shown that the seed germination rate was decreased by the increased concentration of white cabbage post-harvest leaves extractions, which were made with different concentrations of aqueous and methanol...

The study was aimed at assessing the yield and quality of winter wheat grains inoculated with Beijerinckia fluminensis (Azotovit) and Paenibacillus mucilaginosus (Phosphatovit) in a three-year experiment on leached Chernozem in the forest-steppe zone of the Middle Volga region. The seeds of the plants were treated before sowing with microbiological fertilisers, both individually and together at a dose of 2 L/t. Bacteria Beijerinckia fluminensis and Paenibacillus mucilaginosus contained in fertilisers increased the resistance of plants to adverse conditions: seedling completeness increased by 5.4%, winter hardiness...

The experiment aimed to obtain a quadratic regression mathematical model of the comprehensive evaluation score of yield, quality, and four macroelements (N, K, P and Ca). The suitable nutrient solution was chosen and verified via computer simulation of the model and the highest comprehensive score in all treatments. Results showed that P, K and Ca had a positive effect on the comprehensive evaluation value of tomato, whereas N showed a negative effect. The optimal formula calculated using the regression equation could promote high-yield and high-quality tomato. The single-plant yield, soluble protein, vitamin C, total sugar, lycopene, and...

The effect of FP (a flat plot without mulch), FPM (a flat plot with film mulching), RM (on-ridge planting with full film mulching), and FM (on-furrow planting with full film mulching) on the tuber and its storage quality of continuous cropping potatoes was investigated. The results showed that with the increase of continuous cropping years, the potato yield was reduced year by year. The furrow-ridge mulching film can significantly increase potato yield and reduce small tubers. Among them, the yield of RM was the highest. From the perspective of tuber quality, RM had the highest dry matter content and starch content, while FP had the lowest. Meanwhile,...

Labile carbon (C) is a major source of C loss because of its high vulnerability to environmental change. Yet its potential role in regulating soil organic carbon (SOC) dynamics remains unclear. In this study, we tested the effect of physical disturbance on SOC decomposition using soils from two abandoned farmlands free of management practice for more than 28 years. The soil respiration rate was measured in undisturbed and disturbed soil columns and was inversely modeled using the two-compartment model. We found that the C loss was 16.8~74.1% higher in disturbed than in undisturbed soil columns. Physical disturbance increased the total amount of labile...

Glomalin is one of the factors with an important role at forming and stabilising soil aggregates. Long-term stationary experiments were carried out to observe the influence of various fertilisation treatments on the content of glomalin in topsoil. The content of easily extractable glomalin (EEG) and total glomalin (TG) were determined. Moreover, glomalin was also determined by using the near-infrared reflectance spectroscopy (GNIRS). Both mineral and organic fertilisation significantly increased the content of glomalin compared to the unfertilised control. However, observed differences among individual...

We studied the dynamics of soil organic carbon (SOC)-pool mineralisation in agricultural soil. A laboratory incubation experiment was conducted using the soil from a long-term experiment involving the following fertilisation regimes: no fertilisation (CK); mineral (NPK); organic (M), and combined organic-inorganic fertilisers (MNPK). SOC mineralisation rate decreased as follows: MNPK > M > NPK > CK. Cumulative SOC mineralisation (Cm) ranged between 730.15 and 3 022.09 mg/kg in CK and MNPK, respectively; 8.81% (CK) to 20.45% (MNPK) of initial SOC was mineralised after a 360-day incubation. Soil...
