“…In particular, research has shown that some cover crops can provide at least part of the mineral N needed for optimum crop yield, leading to possible reductions in the amount of synthetic N fertilizer applied to agricultural fields. In addition, slow-degrading cover crop plant materials such as rye (Secale cereale L.) release mineral N in synchrony with N demand of growing crops and thus enhance N uptake 32 . These results argue for the supplementation of NT farming with other strategies to enhance N use efficiency and reduce diffuse N pollution.…”

Although no-till (NT) has been promoted as an alternative land management practice to conventional tillage (CT), its impact on water quality, especially nitrate (NO3 −) loss remain controversial. We conducted a meta-analysis to compare NO3 − concentration and load in NT and CT systems via two major transport pathways: runoff and leaching. Rainfall variability, aridity, soil texture, tillage duration, crop species, and fertilizer type were used as co-varying factors. In comparison to CT, NT resulted in an overall increase of runoff NO3 − concentration, but similar runoff NO3 − load. In contrast, leachate NO3 − load was greater under NT than under CT, although leachate NO3 − concentration was similar under both tillage practices, indicating that the effect of NT on NO3 − load was largely determined by changes in water flux. Some deviations from these overall trends, however, were recorded with different co-varying variables. In comparison to CT, NT, for example, generated lower leachate NO3 − concentration and similar (instead of elevated) NO3 − leachate load from soybean fields (no N fertilizer applied). These results suggest NT needs to be complemented with other practices (e.g., cover crops, reduced N rate, split N application) in order to improve soil N retention and water quality benefits.

“…In contrast, the decrease was significantly different from the increase in the proportion of sago pulp waste in the mixtures. Maize growth experiences a vegetative growth phase from week 4 until the plant enters the final vegetative stage at 8 weeks after planting, where the plant's need for nitrogen is very high (Ladan and Jacinthe, 2017). Nitrogen is an essential constituent of amino acids, amides, nucleotides and nucleoproteins, and is essential for cell division, cell enlargement and growth.…”

The agricultural sector is the mainstay of the economy in Central Moluccas. However, most agricultural soils on the island have low soil fertility. One of the efforts that farmers can make to improve soil fertility is to apply organic matter, which is widely found in Central Moluccas. This study aimed at elucidating the effect of mixing high-quality organic material (Glicidia sepium pruning) with low-quality organic material (sago pulp waste) on the improvement of available nitrogen in an acid soil (Dystrudept) and growth of maize. Two experiments were carried out in a laboratory and a greenhouse. The compositions of the mixtures of sago pulp waste (A) and pruning of Gliricidia sepium (G) were A0 G100; A20G80; A40G60; A60G40; A80G20, and A100G0. Six treatments and one control (no application of residues) were arranged in a completely randomized design. The results showed that the application of the mixture of 20% and 80% of Gliricidia sepium pruning (A20G80) increased the cumulative amount of mineral N in the soil higher than that of the other organic material mixtures, which in turn improved maize growth.

“…Due to its high yield, fodder advantages and adaptability to cultivation, this crop is grown in different regions of the country. The most important factor that determines the yield of agricultural crops is mineral nutrition [1][2][3]. When cultivating maize, it is important to apply the necessary treatment to the plants in the required amount and the optimal ratio of basic nutrients and microelements.…”

The most important factor that determines the yield of agricultural crops is mineral nutrition. It is important to supply the plants in the required amount and the optimal ratio of basic nutrients and microelements. Foliar treatment is the most rational way to apply micronutrient fertilizers. The current research aimed at examining the species (Azosol 36 Extra, 3.0 l/ha; Aquarin 5, 3.0 l/ha) and the terms of application (5 maize leaves; 8 maize leaves; 5 leaves + 8 maize leaves) of micronutrient fertilizers, depending on the early ripening of the hybrid, providing the formation of the best indicators of photosynthetic activity, was carried out on leached heavy loamy chernozem. When foliar treatment of an early ripe hybrid with Azosol 36 Extra solution, the increase in the total leaf surface of sowing in relation to options with water on a natural agro background was 3.0%, and from Aquarin 5-9.1%, and for the mid-early, the increase was 4.3 and 6.9%, respectively. Against the background of N110P70K40, the gains varied from 4.0 to 5.9%, but no significant advantage, both types of micronutrient fertilizers and in terms of foliar treatment, was not revealed. The use of Azosol 36 Extra on the natural agro background promoted an increase in the total photosynthetic potential by 2.7-4.1% compared to the treatment with water, the effect of Aquarin 5 was more effective, the increase was 6.9-8.9%. With the improvement of root nutrition conditions, the increase from Azosol 36 Extra was obtained a bit more - 4.1 -5.8%, and from Aquarin 5, on the contrary, less (3.7-5.6%). Variants with foliar treatment with Azosol 36 Extra in the phase of eight leaves and double application, the increase varied from 7.5-7, 9% on a natural agricultural background to 13.2% on an improved one. Aquarin 5 had a better effect on plants during foliar treatment in the phase of five leaves of maize, but the increase was 2.7-8.5%.
