This factsheet provides information about the history of soil testing calibrations and justification for recommending extraction nutrients using Mehlich-3 calcareous soils in Miami-Dade County. The dominant from this County have an extraordinarily high concentration calcium resulting pH. document also includes UF/IFAS approved extractant-based interpretations recommendations these soils. purpos...

A field experiment was carried out to investigate the effects of vermicompost (0, 10, and 15 tha-1), climatic elements i.e. soil moisture (50%, 70%, 100%) elevation temperature (1 20C) on physico-chemical properties nutrient availability post-harvest calcareous-acid mixed soils after rice production. total 18 treatments assembling afore-mentioned doses applied. The analyses demonstrated signifi...

The decomposition of organic matter in coarse sandy calcareous soils (beach sand) is thought to be much higher than in acid fine sandy soils but relatively little research is performed on these soils. Laboratory incubation experiments in which the release of soil carbon (C) is determined may overestimate the release of the soil organic C, as part of the measured C may have been released from th...

With the global population predicted to grow by at least 25% by the year 2050, the sustainable production of nutritious foods will be necessary for human health and the environment. Iron (Fe) is an essential nutrient for both plants and humans. Fe is poorly soluble, especially at high pH levels, at which it is difficult for living organisms to accumulate sufficient Fe. In plants, Fe deficiency ...
