“… 1 The most commonly used commercial fertilizers are single superphosphate (SSP), triple superphosphate (TSP), urea, nitrogen–phosphorous–potassium (NPK), monoammonium phosphate (MAP), and diammonium phosphate (DAP), which supply the basic plant nutrients such as nitrogen, potassium, and phosphorus. 2 The application of these fertilizers results in huge economic losses due to 40–70% of leaching-related problems, which cause dramatic losses in the soil nutrients and decrease the fertility of the soil. 3 Furthermore, the use of large-scale commercial fertilizers for a long period is not an appropriate process to enhance the crop productivity because it causes remarkable damage to the soil microbial flora, soil structure, plants, and even to the ecosystem.…”

In this work, we have proposed a new formulation of a hybrid nanofertilizer (HNF) for slow and sustainable release of nutrients into soil and water. Urea-modified hydroxyapatite was synthesized, which is a rich source of nitrogen, calcium, and phosphate. Nanoparticles such as copper, iron, and zinc were incorporated into urea-modified hydroxyapatite to increase the efficiency of the proposed fertilizer. Different techniques including powder X-ray powder diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy were used to get insight into the properties, morphology, and structure of the as-prepared fertilizer. The developed HNF was used in a field experiment on the ladies’ finger ( Abelmoschus esculentus ) plant. The slow release of HNF was observed during leaching studies and confirmed the availability of Ca 2+ , PO 4 3– , NO 2– , NO 3– , Cu 2+ , Fe 2+ , and Zn 2+ . Furthermore, the presence of Cu 2+ , Fe 2+ , and Zn 2+ nutrients in ladies’ finger was confirmed by the inductively coupled plasma-optical emission spectrometry (ICP-OES) experiment. A considerable increase in the physicochemical properties such as swelling ratio and water absorption and retention capacities of the proposed fertilizer was observed, which makes the fertilizer more attractive and beneficial compared with the commercial fertilizer. The composition of the proposed HNF was functionally valuable for slow and sustainable release of plant nutrients. The dose of prepared HNF applied was 50 mg/week, whereas the commercial fertilizer was applied at a dose of 5 g/week to A. esculentus . The obtained results showed a significant increase of Cu 2+ , Fe 2+ , and Zn 2+ nutrient uptake in A. esculentus as a result of slow release from HNF.

“…Mineral fertilization is one of the most important factors in the intensification of plant production. This factor has a significant impact on the productivity and quality of the harvested products [4,5,22,29,43]. At the same time, it is worth emphasizing that the irrational use of fertilizers (both in excess and in a too small amount) is ineffective.…”

Balanced, rational fertilization determines high and valuable yields of crops. Polish agriculture has been considered traditional, pro-ecological, with relatively low consumption of agrochemicals for many decades. Transformations in the economic and social area, in particular Poland’s accession to the European Union, have significantly changed this picture. This paper presents the results of the research on the trends in fertilizer consumption in the Polish agriculture. The main time range of the analyses covered the period of 2013–2017. The source materials used in the study were statistical data for the entire country and provinces, published by the Central Statistical Office (GUS), as well as results of empirical studies. According to analyses, the pressure associated with the increase in the use of mineral fertilizers in Poland is growing. In the economic year 2017/2018, the average consumption of mineral fertilizers in Poland was at a level of 141.6 kg NPK per hectare of agricultural lands and was higher by 39.2 kg than in the 2004/2005 season. The empirical studies were carried out in six randomly selected provinces in Poland. Total 1034 surveys completed by farmers were analysed. Comparative analyses were carried out using a multiple correspondence analysis (MPA). Based on the analysis performed, it can be stated that the direction of changes in the consumption of fertilizers depends on the area and economic size of the agricultural holding as well as on the district in which the agricultural holding is located. The article points out problems in the area of sustainable fertilizer consumption in Poland (high consumption of nitrogen fertilizers, low level of soil liming, etc.). Perspective directions of changes (precision agriculture, innovative fertilizers, increased farmers’ awareness of nutrient efficiency and reduction of negative impact on the environment) were also summarized.

Potential Sustainable Slow-Release Fertilizers Obtained by Mechanochemical Activation of MgAl and MgFe Layered Double Hydroxides and K2HPO4

This study describes the behavior of potential slow-release fertilizers (SRF), prepared by the mechanochemical activation of calcined Mg2Al-CO3 or Mg2Fe-CO3 layered double hydroxides (LDH) mixed with dipotassium hydrogen phosphate (K2HPO4). The effects of LDH thermal treatment on P/K release behavior were investigated. Characterizations of the inorganic composites before and after release experiments combined X-Ray diffraction (XRD), Fourier-transform infra-red spectroscopy (FTIR), solid-state nuclear magnetic resonance (NMR), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The best release profile (<75% in 28 days and at least 75% release) was obtained for MgAl/K2HPO4 (9 h milling, 2:1 molar ratio, MR). Compared to readily used K2HPO4, milling orthophosphate into LDH matrices decreases its solubility and slows down its release, with 60% and 5.4% release after 168 h for MgAl/K2HPO4 and MgFe/K2HPO4 composites, respectively. Mechanochemical addition of carboxymethylcellulose to the LDH/K2HPO4 composites leads to a noticeable improvement of P release properties.
