“…The value of agronomic efficiency index for cereal production in developing countries ranges from 10 to 30 kg of a product • kg -1 nitrogen fertilization (Dobermann, 2007). The value of agronomic efficiency index in individual variants of the experiment ranged between 6.16 and 35.92 kg • kg -1 expressed as Chinese cabbage dry matter yield, whereas Niemiec et al (2015a) reported the value of this parameter in conventional cultivation of celery to be approximately 20 kg • kg -1 . The manner of application of nitrogen fertilizers is one of the most effective methods of improving the efficiency of fertilizer nitrogen utilization.…”

“…The slow-acting fertilizer was applied pointwise and in rows, approximately 5 cm below plant roots. Using slow-acting fertilizers directly under the root limited plant growth and increased differences in the size of individual plants, which is unfavorable from the point of view of the commercial quality of the product (Niemiec, 2014;Niemiec et al, 2015a). The experiment was set up on soil with the granulometric composition of sandy loam.…”

“…From the point of view of present-day quality standards in primary production, the agricultural system should be assessed using not only production indicators but also environmental indicators (Verzeaux et al, 2017). The manner of fertilizer application is of great importance for reaching set production and environmental goals which are always connected with an increase in fertilization efficiency (Mucheru-Muna et al, 2010;Niemiec et al, 2015a;Nkebiwe et al, 2016). Productivity rate informs how much has plant yield increased after application of 1 kg nitrogen in the form of fertilizer.…”

The study aimed to assess the suitability of slow-release fertilizers in cultivation of napa cabbage in the integrated production system. The objective was realized on the basis of a strict field experiment set up on soil with granulometric composition of light loam. The dose of fertilizer was the first experimental factor, and the fertilizer application was the second factor. The slow-acting fertilizer was applied under each plant during planting of seedlings and in the second variant. The fertilizer was applied in the row, about 5 cm under the seedling root level. On the basis of the results obtained in the experiments, the indices showing nitrogen fertilization efficiency were calculated Fertilization significantly modified the quantity of obtained yield. In the control, without mineral fertilization, the crop yield was 23.32 Mg ha -1 . The largest yield was 52.27 Mg ha -1 . Larger yields and more advantageous productive and environmental efficiency were obtained in objects with row application of fertilizer. The most advantageous agronomic efficiency and nitrogen recovery efficiency were obtained in the combination of 400 kg ha -1 of slow-acting fertilizer with traditional supplementary PK fertilizers in the case of point application of fertilizers. In the case of row fertilizer application, it is possible to use 50% more of the fertilizer dose without compromising the quality of the crop. Higher doses of free-acting fertilizers increased the standard deviation of the mass of cabbage, which is not desirable for production. The results show that under conditions of low mineral content in the soil, the slow-acting fertilizers can be used at a low level.

“…With the optimization of maize fertilization technology, the value of the discussed parameter increased from 37 kg N·kg-1 to 59 kg N·kg −1 under nitrogen fertilization at 140 kg N·kg −1 [24]. Niemiec et al [32] reported values of the efficiency coefficient of celery from 19.35 to 151.76 kg, depending on the fertilization variant, under intensive production conditions on a soil with high agronomic suitability. Amanullah and Almas [33] determined the value of this parameter at 28 to 55 kg·kg −1 of grain, depending on the applied fertilization strategy, while Li et al [34] achieved a more than double increase in the value of the productivity coefficient when introducing nitrogen fertilizers through the root.…”

Optimization of plant nutrition is a very important part of primary production quality systems. Crop fertilization is the most important agrotechnical measure because it determines the amount and quality of the yield. Moreover, excess fertilization intensifies the eutrophication processes and the greenhouse effect. The study aimed to assess the suitability of slow-release fertilizers in cultivation of carrot subspecies Daucus carota L. ssp. sativus in the integrated production system. The objective was realized on the basis of a strict field experiment set up on a clay loam soil with low nutrient content. The dose of fertilizer was the experimental factor. The fertilizers were applied during the formation of the ridges. Traditional fertilizers (ammonium phosphate, potassium salt, ammonium nitrate, and a multi-component fertilizer Polifoska 6), as well as a multi-component fertilizer with slow release of nutrients, NPK Mg (18-12-24-4), were used. In individual variants of the experiment, different fertilization strategies were applied: integrated production fertilization, traditional fertilization, and fertilization based on the use of slow-release fertilizers. The control treatment comprised of unfertilized plants. The efficiency of nitrogen fertilization was evaluated based on agronomic efficiency, partial factor productivity, physiological efficiency, and removal efficiency. Fertilization strategy significantly impacted the quantity of obtained yield. In the control sample, prior to mineral fertilization, the crop yield was 33.53 Mg·ha −1 . The largest yield was 82.30 Mg·ha −1 .The largest yields were obtained from plants fertilized with a combination of slow-release fertilizers, with nitrogen introduced in the form of ammonium phosphate, and through conventional fertilization. The highest productivity and environmental efficiency were obtained in treatments with fertilization according to the principles of integrated production and with slow-release fertilizers. In terms of environmental efficiency, the best results were obtained through nitrogen fertilization using 400 kg of slow-release fertilizers. The use of slow-release fertilizers in carrot cultivation can significantly improve the efficiency of fertilization, both in terms of production and environmental protection.

Food production is one of the most important sources of greenhouse gas (GHG) emissions, both in primary production and in processing and the logistics chain. The most problematic and risky is the optimization of environmental effects in the stage of primary production. This is due to the significant influence of factors related to climate and soil that are difficult to predict. The scientific literature offers much information on the impact of crop residue management, but the context for assessing the impact of crop residue management in corn production on the carbon footprint is still unclear. The effectiveness of using organic additives like biochar, compost, corn, or straw to maintain soil productivity is well acknowledged. Information about the effects of particular crop residue management strategies on soil carbon sequestration, soil quality, and crop yield in corn cultivation is currently scarce. The research aimed to assess the potential for optimizing corn production through modifications in crop residue management, with a focus on the efficiency indicator being the level of greenhouse gas emissions per functional unit of the product. A 3-year growing experiment was conducted to investigate the impact of different corn crop residue management strategies. The modifications of the corn cultivation technology in terms of the crop residue management strategy had a significant impact on the yield of plants and the amount of GHG emissions. The conversion of corn straw to biochar and its introduction into the soil reduced the GHG emissions from corn cultivation per functional unit, despite the energy expenditure related to straw transport and biochar production. From a 3-year time perspective, a beneficial effect of biochar addition on the size of the commercial yield of plants was observed. In variants with biochar and a reduced level of nitrogen fertilization, no reduction in yields was observed. This confirmed the hypothesis that biochar could be a useful material for the production of slow-acting fertilizers.
