Abstract:

Fertilizer demand updating has a good practical significance to direct agricultural yield and for notifying the growth in market price of fertilizer to the farmer. In this the data analysis technology is used to update the rate change via notification. When the fertilizer value changes market gets the notifications for different types of land states. Fertilizers quality is pick out by ranking process. By this process the rate of the low and high qualities fertilizer is informed. The usage of number of classifiers provides a way to make good decision on prophecy due to the usage of multiple cla

Abstract:

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

Total fruit biomass was higher in mineral fertilized plants compared to urine fertilized and non-fertilized pumpkins. Urine fertilized pumpkins may have suffered from lower potassium or higher chloride, thus they produced fewer flowers and fruits. However, total fruit biomass and the number of fruit

Abstract:

Fertilizer prices have risen worldwide since the end of 2021. In this context, the value of organic fertilizers has also changed from the farmers’ perspective. Hence, an open question about their value arises with an increased demand for organic fertilizers. This question must be addressed individually for each farm. Hence, a linear optimization model is applied. The model can be adapted to farm conditions and provides mineral and organic fertilizers as plant nutrition variables. The price level at which an organic fertilizer becomes competitive within the farm can be identified by parameteriz

Abstract:

Farmers' knowledge of the amount and dosage of fertilizers recommended for a practical fertilization system is low. As the result, the plant does not fully absorb the given fertilizer. Some fertilizers are leached by the flowing water and wasted into the soil layer. In long term basis, this practice can cause environmental pollution, especially on the land, water and air. Due to this fertilization problem in agriculture practice, a material with a high-water absorption capacity, which further releases it together with the fertilizer over a desirable period of time, is needed.

Abstract:

Homeowner surveys conducted in Edina, Minn., showed varying levels of horticultural knowledge on lawn care. A majority of consumers, 75%, knew the value of lawn clippings was equivalent to one fertilization treatment, but 72% did not know the amount of fertilizer needed for a medium maintenance lawn. A total of 77% indicated spring as the single best time to control broadleaf weeds, and 39% thought spring was the best time to fertilize, whereas 48% indicating fall as the best time to fertilize. Current practices included the following: leaving clippings on the lawn, 75%; bagged and removed cli

Abstract:

In a circular economy framework, waste valorization in crop production promotes sustainability in the agricultural sector. Buckwheat (BW; Fagopyrum esculentum Moench) has promising nutritional and economic value. Its sustainable production can be promoted by applying organic fertilizers. Aimed at determining the effect of a bio-stabilized municipal solid waste (MSW) amendment on BW, a greenhouse experiment was performed combining two different soils (clay and sandy) with three previous fertilization treatments (no fertilizer, mineral fertilizer, or MSW fertilizer) from the precedent faba bean

Microbial fertilizers are already common practice (e.g. Bloom® and Synagro); yet microbial fertilizer blends to align the nutrient release profile to the plant’s needs are, thus far, unexplored. Moreover, most research only focuses on direct fertilization effects without considering added value properties, such as disease prevention. This study has explored three promising types of
