This study aims determine soil quality, limiting factors, mapping and provide management directions or recommendations. research was conducted the rice fields from November 2020 January 2021. using survey methods, analysis laboratory, determination...

The excessive use of chemicals in plant production, including mineral fertilizers has a harmful effect on the morpho- and physiological state strawberry plants, their yielding, physicochemical properties fruit soil. Increasing effectiveness beneficial microorganisms, i.e. filamentous fungi, arbuscular mycorrhizal fungi (AMF) bacteria, is an essential method reducing amount used to fertilize aim...

Despite policies inplemented to minimise Swidden Agriculture (SA) practices, it remains in semi-arid areas of Timor Island. A study SA was conducted Manikin Watershed (MW) West during 2017 2019 oder understand the nature using Agro-ecosystems approach and analyse strengths for sustainable upland farming management. The research applied survey method data collection. Qualitative analysed themati...

Iron release from melting continental and sea ice is deemed important for phytoplankton, the growth of which iron-limited in Southern Ocean. Both sources are generally considered separately, yet their effects on biological carbon pump could interact. Using a global ocean-sea-ice-biogeochemical model with representation both iron sources, we find them to have an overall additive effect phytoplan...

Driscoll et al. (1) have recently drawn attention to the risk of new pasture plants becoming invasive, because the same biological traits that promote pasture productivity may also facilitate the invasion of natural areas. The authors indicate some aspects that could mitigate the risk of invasion: namely, the use of native species to develop new pasture plants, the avoidance of new characterist...

Abstract Nowadays, phosphorus natural reserves are being depleted, while P fertilizers demand is increasing. Phosphorus well contained in waste materials such as sewage sludge. Only a small amount (1–3%) of the soil total bioavailable for plant nutrition. More detail, present study focuses on determination kinetics concentrations sandy calcareous after application A centrifuged (C) and dried (D...

Among deciduous fruit crops, maximum sustained yields under ideal conditions reportedly range from 22 MT/ha in sweet cherry to 112 MT/ha in apple: about a 5-fold difference. Root length densities under fruit trees, however, range from about 0.2 km/m in apple to about 12 km/m in kiwifruit: a 60-fold difference. What causes these differences among the root systems of different fruit crops? Patter...
