Resumen

This paper reports the design, fabrication and testing of a low-cost PVC-based manual fertiliser applicator (MFA) for the placement of granular and powdery fertilisers (organic and inorganic) at a required soil depth and plant spacing. The MFA consists of a spring-loaded trigger mechanism, a connecting tube and a knapsack plastic tank for the fertiliser storage, holding between 8.0–12.0 kg of fertiliser depending on the fertiliser's characteristics. The MFA was tested using four common fertilisers (NPK, SSP, Urea and organic manure) at different fertiliser moisture contents (3, 4, 5 and 6% w.b

Resumen

Cow manure converted into organic fertiliser is of good quality and has a high sales value. The use of faeces and urine as organic fertiliser is very beneficial, especially for soil fertility, and provides the necessary nutrients for plants. The village of Alebo has a majority of farmers, so fertilizer is the main need for the management of crops such as rice, maize, sweet potato, beans and other crops, as well as in the surrounding village communities, which also have a majority of rice fields and are farmers. Urban communities also need fertilizers to fertilize ornamental plants in their gar

Resumen

Application of Mg fertilisers has been suggested as a means of reducing the incidence of Mg deficiency of forest trees in New Zealand and Europe. The objective of this study was to determine the rates of dissolution of a range of Mg fertilisers applied to a pumice soil (Typic Udivitrand). The rate of fertiliser dissolution was little influenced by whether the fertiliser was applied directly on to the soil surface (litter removed) or on to the litter layer in a Pinus radiata plantation. Twenty-seven months since fertiliser application the mean (with and without litter) percentage of Mg dissolve

AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximat

The study examined rice farmers’ fertiliser purchasing behaviour and the impact of various fertiliser regimes on rice growth, yield, and grain nutrient content. Additionally, a field experiment using a randomised complete block design tested four treatments: no fertilizer (control), NPK20:10:10 (farmer’s practice), NPK20:10:10 + Single Superphosphate (SSP), and Urea + SSP. Results showed that while Urea + SSP improved growth metrics, NPK20:10:10+SSP achieved the highest grain yield (81 kg/plot) and 1000-seed weight (24.67 g), alongside elevated levels of iron and zinc, addressing both yield ga

Resumen

Fluoride (F) is an impurity in phosphatic fertilisers and significant amounts of F will be added to soils with long-term application of phosphatic fertiliser to soil. There is a risk that F concentrations in soil may increase to levels toxic to plants or grazing animals. If F added to soil remains in the upper soil profile, due to high reactivity with soil, grazing animals could increase their intake of F through inadvertent ingestion of F-enriched soil. This study determined the distribution of F in the soil profile of medium (>8 years) and long-term permanent pastures (>50 years) where

Modern agriculture faces a major challenge in maintaining high productivity while preserving the environment. In recent decades, the use of synthetic chemical fertilisers has become a common practice worldwide to increase crop yields (Sari, 2023). This research aims at analysing the effect of organic fertiliser use on plant and soil quality. This research uses a quantitative method with a field experimental approach. This approach was chosen because it allows researchers to directly measure the effect of organic fertiliser use on soil quality and plants under environmental conditions. From the

Resumen

Abstract A possible way to increase the operating speed and field capacity of a cultivator-fertiliser is to modify its configuration scheme. According to our hypothesis, placing the fertiliser hopper directly on the tractor frame could reduce the traction resistance of the cultivator-fertiliser and consequently increase its operating speed and field capacity. Validating this hypothesis requires a comparative evaluation of the existing configuration schemes for cultivator-fertilisers. However, there are currently no such comprehensive studies available.

Resumen

Robusta coffee cultivation in Pagar Alam City has not been carried out optimally because most farmers do not practice precision farming patterns in the use of production inputs to increase coffee plant productivity, including the use of unsubsidised coffee-specific fertilisers. In order to be accepted by farmers, fertiliser companies must pay attention to the willingness to pay of farmers for these fertilisers. For this reason, the study aims to: (1) determine farmer perceptions of nutrient content, ease of use and quality of fertiliser, (2) determine the value of farmers’ willingness to pay f

Abstract Aims Grasslands are important agricultural production systems, where ecosystem functioning is affected by land management practices. Grass-legume mixtures are commonly cultivated to increase grassland productivity while reducing the need for nitrogen (N) fertiliser. However, little is known about the effect of this increase in productivity on greenhouse gas (GHG) emissions in grass-legume mixtures. The aim of this study was to investigate interactions between the proportion of legumes in grass-legume mixtures and N-fertiliser addition on productivity and GHG emissions. We tested the h

Pak-choi (Brassica chinensis L.) is one of the most widely consumed leafy green vegetables. In hydroponics, the growth depends upon the composition of nutrient solutions. This study was conducted due to the lack of reported studies on the effect of nutrients towards the hydroponic pak-choi plant. Therefore, this study describes the impact of different types of nutrients on plant growth. The response of the pak-choi plant growth upon the number of leaves per plant, plant height and leaves diameter were measured.

Sugarcane crops typically have a high fertiliser nitrogen (N) input, with low N recovery efficiencies. Nitrogen is essential to crop productivity, but excess application can have negative environmental consequences. Despite the importance of coordinating N fertiliser input with crop N requirements, certain components of the sugarcane plant are typically not considered when evaluating N nutrition. The objective of this study was to establish which sugarcane crop components should be included in these evaluations given their impact on N mass accumulation and on fertiliser N recovery efficiencies

Purple sweet potatoes (Ipomoea batatas) have captured the attention of nutritionists and food enthusiasts alike for their rich anthocyanin content, contributing to their vibrant hue and potential health benefits. However, purple sweet potato is not as popular as the orange and white varieties because of the high anthocyanin content, which may cause the purple sweet potato to taste less sweet than the other varieties. The purple sweet potato, known as Lembayung, has a high anthocyanin content (3.19-7.05 mg/100g) and tastes less sweet than other commercial varieties. Enhancing its’ sweetness wil
