Pineapple Leaves

Due to the 1997/98 haze problem in South-East Asia and the increasing need for sustainable food production and development, the usual management of crop residues (including pineapple wastes) through burning is prohibited. As a result, the need for alternative uses of pineapple wastes in pineapple production has been emphasized. This study investigated an environmentally friendly means of recycling pineapple leaves for agricultural use. Pineapple leaves were shredded and composted in a composting drum for 30 days. Part of the shredded leaves was ashed in a muffle furnace for 4 h. Humic acid (HA), K-fulvate, and K in HA and compost were analyzed using standard procedures. An ash to water ratio of 1:7 was used to extract 0.1 molar (M) KOH from the shredded leaves. The 0.1 M KOH contained 50% K and was able to extract 20% HA from the composted pineapple leaves. Percent K in the fulvate using 0.1 M KOH was 43. Besides serving as a foliar spray (supplement soil application K fertilizers), source of K for freshwater fish (e.g., tilapia), the HA produced can be used as a soil conditioner. Studies show that between 0.05–0–01 g of HA per kg soil retards runoff by 36% in sandy and sandy loam soils. The K-fulvate can be used as a fluid fertilizer. In addition, the pH of 2 of the K-fulvate suggests it could be used to dissolve phosphate rocks, particularly those in the arid regions where high soil pH does not facilitate the dissolution of these important rocks that serve as one of the sources of phosphorus fertilizer in agriculture.

<p>Halting and reversing soil degradation as well as protection and sustainable use of soil as a resource are part of the United Nations Sustainable Development Goals. Despite the vital significance and essential functions of soil, massive amounts of fertile soil worldwide are lost due to improper land use. In Germany, approximately 66 ha of soil are damaged partly or completely in their soil functions daily. The main issues are soil erosion, land area claims for housing estate and transportation, and pollution. Until now, precise spatial location and assessment of the loss of valuable soil in terms of fertility and productivity has not been quantifiable and therefore not controllable.</p><p>In the SOIL-DE project, indicators to evaluate the functionality, potential, intensity of use, and vulnerability of soils are developed in order to be able to assess the quality and value of soils, both in retrospective and under current agricultural use. The aim of this survey is (i) to detect the loss of land over the past ten years in high spatial accuracy, (ii) to determine the fertility of the soil and (iii) to identify risk areas, i.e. regions with particularly high soil loss rates and high soil profitability. The threat to soil, the fertility and impairment of soil functions by changes in land use, are to be recorded nationwide and statewide. Therefore, the evaluation of time series from satellite images is used in combination with official soil information at different spatial resolution, as well as digital elevation models and climatic data. In this study, different rating systems are investigated including e.g. the Muencheberg Soil Quality Rating (ZALF), biotic potential yield, resistance to erosion, filter, buffer and transformation function, and runoff regulation. First results will be presented.</p>

AbstractVermiculite minerals are locally available in the Mozambique Belt of Tanzania but are not currently commercially exploited. In part this may be due to lack of any precise characterization. This study was carried out as a first step to assess the suitability of these vermiculites for crop production by characterization of their mineralogical and chemical compositions. X-ray diffraction and scanning electron microscopy combined with an energy-dispersive X-ray system were used to establish the mineralogy. Electron microprobe analysis and inductively coupled plasma-mass spectrometry were used to study the chemical compositions and to identify any possible issues related to chemical composition that might affect their use if applied as soil conditioners. The samples were characterized as vermiculites and hydrobiotites with a wide variety of accessory minerals. Accessory minerals that might be of some concern are galena, fibrous amphiboles and sepiolite. The total levels of Ni in all vermiculites, and Cr in some, were also found to be high relative to common European standards and this might limit their potential as soil conditioners. It is clear that a field assessment of the bioavailability of various elements would be necessary before decisions relating to potential agricultural use could be made.

Whether modern agriculture without conventional pesticides will be possible or not is a matter of debate. The debate is meaningful within the context of rising health and environmental awareness on one hand, and the global challenge of feeding a steadily growing human population on the other. Conventional pesticide use has come under pressure in many countries, and some European Union (EU) Member States have adopted policies for risk reduction following Directive 2009/128/EC, the sustainable use of pesticides. Highly diverse crop production systems across Europe, having varied geographic and climatic conditions, increase the complexity of European crop protection. The economic competitiveness of European agriculture is challenged by the current legislation, which banned the use of many previously authorized pesticides that are still available and applied in other parts of the world. This challenge could place EU agricultural production at a disadvantage, so EU farmers are seeking help from the research community to foster and support integrated pest management (IPM). Ensuring stable crop yields and quality while reducing the reliance on pesticides is a challenge facing the farming community is today. Considering this, we focus on several diverse situations in European agriculture in general and in European crop protection in particular. We emphasize that the marked biophysical and socio-economic differences across Europe have led to a situation where a meaningful reduction in pesticide use can hardly be achieved. Nevertheless, improvements and/or adoption of the knowledge and technologies of IPM can still achieve large gains in pesticide reduction. In this overview, the current pest problems and their integrated management are discussed in the context of specific geographic regions of Europe, with a particular emphasis on reduced pesticide use. We conclude that there are opportunities for reduction in many parts of Europe without significant losses in crop yields.

In this article the results of synthesis of monocalcium phosphate with a zinc phytocompound are considered. By studying the chemical interaction of monocalcium phosphate with a zinc phytocompound, studying their physicochemical and commercial properties, the optimal compositions of phosphorus fertilizers based on monocalcium phosphate with a zinc phytocompound have been determined. Considering the importance of phosphorus for the formation of plant tissue in increasing the productivity of agricultural crops, the main attention is paid to the assi-milation of phosphorus compounds by plants, which is of paramount importance. It is well known, that one of the main disadvantages of phosphorus fertilizers used in crop production is the low utilization rate of nutritive phosphorus pentoxide, which does not exceed 20-22%. The fact of the low utilization rate of nutritious phosphorus pentoxide in fertilizers is associated with its retrogradation in the soil with the formation of compounds not assimilated by plants. Agrochemical studies have established that phytocompounds increase the utilization rate of phosphorus-containing fertilizers.

The article presents the results of the agroecological composition of soils for different agricultural uses. Under modern conditions of increasing intensification of agricultural production, the agroecological condition of soils is deteriorating, which increases the risk of obtaining low–quality products. Along with this, there are various problems, such as loss of soil fertility, increased erosion, groundwater pollution and environmental pollution in general. Therefore, there is a need for constant monitoring of agroecological indicators of the soil in the conditions of intensive agriculture and horticulture. The great importance is the problem of finding reserves to increase soil fertility and improve their agroecological condition. Therefore, regular testing of soil nutrients and factors that have a major impact on their availability are extremely important to achieve sustainable levels of crop and fruit production. The main purpose of the research was to study and analyze agricultural lands: arable land and perennial plantations and the main agrochemical indicators of the soil of the central part of Vinnytsia region during intensive agriculture and horticulture. The object of research is the soils of agricultural lands used under intensive horticulture and crop production. The subject of research is the agroecological indicators of soil. The research was carried out in the farm of Agro–Etalon LLC in the village of Vasylivka, Tyvriv district. The soils of agricultural lands used under orchards (apple orchard) and agricultural crops (wheat after sunflower predecessor) were studied for comparison. According to the results of soil analysis, it was found that the highest difference in the studied indicators was found in the exchangeable potassium (К2О), mobile phosphorus (Р2О5), which was observed more in the soils involved in horticulture compared to the soils of field crop rotations. Farm soils with different agricultural uses were characterized by lower humus content. The highest difference in the concentration of chemical metals was found for molybdenum (Mo) and cadmium (Cd), which were more in the soils used in horticulture.

Do So

Crop production needs to double to feed the world’s growing population. Indonesia, as the fourth most populated country in the world, needs to meet its food security challenge with a shrinking arable land area. Indonesia has over 34 million ha of swampland. The scarcity of arable land in Indonesia means wetlands are likely to be converted to agricultural use. The challenge is to both profitably and sustainably do so. This paper presents a framework for developing wetlands for food production, which includes (1) the characterization of land and problem of development; (2) analysis of historical development and lessons learned; (3) technology development; and (4) optimization of development. We analyze each of the components and its relation to regional economic growth and lessons learned. For successful future wetland development, three factors must be considered: Land-soil-water characterization, landscape and land use design, and community development. This framework can be adopted by other tropical areas for the development of wetlands.
