crop nutrient deficiency Articles

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • Characterization of corn Nitrogen status with a greenness index under different availability of Sulfur

    Several methodologies measure leaf greenness intensity and relate it to crop N status. There is no evidence, however, of the utility of this variable to detect N deficiencies in corn (Zea mays L.) under S deficiency. The objective of this work was to evaluate the potential of two indexes based on leaf greenness intensity to detect N deficiencies in corn under different levels of S. Two ...

  • Effect of deficit irrigation and fertilization on cucumber

    Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

  • Potassium and winter hardiness

    The role of Potassium in metabolic processes such as protein synthesis and the movement of sugars within the plant is now well understood and recognised as crucial for maximising quality and yield. But it is now known Potassium also plays a significant role in helping crops resist disease and environmental stresses during winter dormancy and ensuring optimum supplies of Potassium to see crops ...

  • Improving soil nutrition with poultry litter application in low-input forage systems

    Despite high volumes of manure production in the Shenandoah Valley of Virginia, there are still areas of forage production that are nutrient deficient because manures have traditionally been applied to higher-value row crops. This study was conducted to compare the effects of poultry litter and inorganic fertilizers on soil fertility and forage production. Two sites had the same treatments ...

  • Farming in a Controlled Environment

    There is considerable pressure on today’s farmers. This is because of farming, as a special type of manufacture, largely depends on climate and natural resources. Climate changes have led to unpredictable weather conditions that can endanger farmer’s efforts with frequent hail, frost or drought. With increased global population, that is predicted to reach a number of 9.6 billion by ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Can superfoods boost the planet’s health, too?

    As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • Farm Practices to Preserve Fruit Quality After Harvesting

    The success of a farmer’s effort in crop production depends largely on the final phase of production, which is often followed by post-harvest losses that can reach up to 50%. Reducing this waste could improve global food production, and increase overall farmer’s profit. Activities that are carried out just before harvesting may have a major influence on final production. Post-harvest ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • What is the Future of Horticultural Science in Africa?

    Horticulture is a labour intensive sector that is important for human wellbeing: 'agriculture supplies protein, carbohydrates and staple crops - but we would have a pretty boring life without horticulture.' Nevertheless, in many countries, faculties of agriculture and their departments of horticulture have been swallowed by schools of life or earth sciences. As a result horticulture gets ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices. These new “soil best management practices” will soon be required by local governments around western Washington, as they update local codes to ...

    "Kenya has a shortage of competent horticultural staff at institutional and commercial levels." "Horticulture is facing a crisis in the United Kingdom." "Is horticulture a withering field in the USA?" "Concerns over shortage of agriculture graduates In Australia." "Uganda's flower sector faces an imminent shortage of qualified managers and supervisors in flower ...
