Aerial Phytomass Production and Growth Performances of Five Common Tall Species in Andean Grasslands at Harvesting and Application of Natural Fertilizers

“…However, the difference in aerial net primary production observed between plots was due to the particular characteristics of each species that were dominant in each particular case such as: the length and width of the leaves, height, and thickness of the stems, the number of bushes, in addition to the soil characteristics [15], in this understanding the first three plots in the production of dry matter, is based on: a) the species C. intermedia and C. antoniana are plants with greater tillering with more solid and thicker leaves and stems that were present in P1, P2, and P3, as opposed to the species C. tarmensis, which is characterized by a morphology contrary to that mentioned by Tovar [33] and was present in plot P4, b) plots P4 and P5 are located on shallower soils with a light brown color, which is indicative of soils with a lower concentration of carbon, organic matter, and nitrogen, due to their higher concentration of silt and clay particles containing Fe oxides [35]. This corroborates that soil characteristics determine not only plant cover but also plant productive capacity [28,29]. Finally, it was found that the harvested dry matter production of leaves and shoot stems were not similar to the original production observed by Yaranga et al [15] who evaluated seven species including the species treated in this research under original conditions and found the following: C. intermedia with a production of 383±18.6 g DM/plant (equivalent to 57.6% more than our result), C. antoniana 313±17.6 g DM/plant (+64.09%), F. rigidifolia 216±23.1 g DM/plant (+62.5%) F. sp 182±24.3 (+68.01%), and C. tarmensis 104±21.6 g DM/plant (+52.5%).…”

“…The application of cattle manure in the subplots also benefited shoot development, although to a lesser extent than rock phosphate. In this case, the beneficiary elements would have been soluble elements such as carbon (C), nitrogen (N), soluble phosphorus (P), and sulfur (S) [28] [29] which were washed away by the rainwater that had started in September and October 2021. The primary element involved in the development mainly of the leaves was undoubtedly nitrogen [30], the intensity of which depended on the asynchrony of the species [27].…”

Effectiveness of Liquid Organic Fertilizer On N-Total of Soil, N, P, K Uptake, and Yields of Peanut (Arachis hypogaea L.) In Inceptisols Jatinangor

“…The availability of nutrients in the soil influences plant nutrient uptake [6]. Soil and organic material were the sources of nutrition for plants [9,10]. Where the process of releasing nutrients into the soil as additional nutrients such as macro nutrients require the decomposition of organic waste previously [11].…”

The Various Forms of Cow Manure Waste as Adsorbents of Heavy Metals

“…A large amount of research has been undertaken to investigate how to decrease the negative impact of manure on the environment, with studies looking at the mechanism of adsorption, specific metal ion binding, cation exchange, precipitation, and complexation [4][5][6][7][8]. There are many forms of manure that can have a positive impact on the environment, such as biochar, compost and humic acid [9][10][11][12][13]. Biochar has great potential for increasing heavy metal immobilization in contaminated agricultural regions [14].Compost has many benefits for soil as a result of its thermophilic aerobic microorganism activity, which converts organic material into a hygienic and biodegradable product [15].…”
