Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

The basic aim of this study was to compare the denitrification efficacy of 2,5-dichloroaniline, Ammonium Thiosulphate and their combination (1:1) with previous studies. Ammonium Thiosulphate was not used as a nitrification inhibitor in previous research. Our findings depict that there was significant variation among the chemicals, soil and levels in denitrification for early seedling growth of wheat.

The research on the structure of the phytoplankton community in relation to the physicalchemical parameters of seawater needs to be carried out to see indicators of fertility and availability of natural food in the waters that will be used as a marine aquaculture location. To find out the relationship between physico-chemical parameters and phytoplankton abundance, Principal Component Analysis (PCA) was used. Some physico-chemical parameters observed were temperature, brightness, pH, salinity, coated oxygen (DO), phosphate, nitrate, and ammonia.

Tomatoes and eggplants are foods that have a lot of nutritional values for humans. Applying farming methods to get good quality products such as being free of pathogenic microorganisms and free of heavy metals needs concerned. In this study, we analyzed cultivation soil and irrigation water samples around tomato and eggplant cultivating areas of farmers who used chemical fertilizers and pesticides.

One experiment was conducted with 3 treatments and 5 repetitions in a completely randomized design. The treatments including TM1: NPK fertilizers; TM2: manure of ducks fed with silaged banana stem (BM); TM3: manure fed with banana stem, molasses and wort (BM-W). The objective was to evaluate the yield of water spinach when applying duck manure fed with banana stem, molasses and wort in replacing the use of NPK fertilizers.

The flood susceptible map was generated by merging the slope map and the stream network maps. The results indicate that about 42.59% of the study area were highly prone to flooding. The areas susceptible to flooding were mainly made up of agricultural lands with high usage of chemical fertilizers for farming, which may leach into nearby rivers, streams, lakes and groundwater during flood occurrence.

The values of potentially mineralizable N estimated using first order kinetics model related well to the observed cumulative MN at 16th week. No significant difference was observed between CF and SRF treatments for available P content in the 2nd week. Significantly higher P content was observed in CF compared to SRF treatment in the 4th week, whereas in the 8th week, some SRFs released significantly higher content than CF.

To the best of our knowledge, no study has investigated replacing chemical fertilizers with fish effluents in marjorana production in a combined aquaculture agriculture system. The main objective of this study was to investigate the effect of Nile tilapia (Oreochromis niloticus) fish effluent water on the growth parameters, herbage yield, and essential oil composition of sweet marjoram.

Soil type is a vital determinant of soil fertility because of its characteristic biological, chemical, and physical properties. However, the soil fertility of upland soil is probably changed by different agricultural management practices regardless of soil type. This study investigated the features of soil fertility (bacterial biomass, total carbon (TC), and total nitrogen (TN)) in upland fields in Japan. One thousand soil samples from different soil types were collected from upland fields located on 36 prefectures in Japan.

Organic agricultural production has been taking place in many countries around the world with a strong shift from traditional agriculture to sustainable agriculture in order to create high-value agricultural products with food safety, environmental protection and climate change adaptation. Organic agricultural production is considered as the natural farming with strict control of irrigation water, unpolluted soil and no use of chemical fertilizers, pesticides, herbicides, growth stimulants and plant varieties, livestock and materials derived from genetically modified organisms.
