NPK macronutrients and microRNA homeostasis
Macronutrients are essential elements for plant growth and development. In natural, non-cultivated systems, the availability of macronutrients is not a limiting factor of growth, due to fast recycling mechanisms. However, their availability might be an issue in modern agricultural practices, since soil has been frequently over exploited. From a crop management perspective, the nitrogen (N), pho...
متن کاملPäätehakkuun ja maanmuokkauksen vaikutus metsän vesi- ja ravinnevirtoihin
Metsä pidättää tehokkaasti siihen laskeuman mukana tulevia ravinteita. Ravinteiden kier to metsässä on yleensä niin suljettua, että niiden huuhtoutuminen laskeumaan verrattuna on vähäistä. Latvusto pidättää osan sadannasta, minkä vuoksi latvuston alla metsikkösadanta on avoimen paikan sadantaa pienempi. Latvustoon pidättynyt vesi haih tuu takaisin ilmakehään. Puusto vaikuttaa metsikkö sadann...
متن کاملA Miniaturized On-Chip Colorimeter for Detecting NPK Elements
Recently, precision agriculture has become a globally attractive topic. As one of the most important factors, the soil nutrients play an important role in estimating the development of precision agriculture. Detecting the content of nitrogen, phosphorus and potassium (NPK) elements more efficiently is one of the key issues. In this paper, a novel chip-level colorimeter was fabricated to detect ...
متن کاملFertilizer NPK from human urine and olive oil mill wastewaters
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
متن کاملEffects of NPK Briquette on Rice (Oryza sativa) in Tidal Flooded Ecosystem
An experiment was conducted at the Bangladesh Rice Research Institute, R/S Sagordi farm, Barisal to evaluate the effectiveness of NPK briquette on rice in tidal flooded soil condition during Boro season, 2010. NPK briquettes of size 2.4 g and 3.4 g were compared with urea super granules (USG) and prilled urea (PU), each supplemented with PKS. The results showed that NPK briquettes, USG and PU p...
