Abstract The purpose of this experiment is to examine the impact of organic fertilisers and biofertilizers on the carbon and nitrogen biomass during the blooming and full maturity stages in broccoli-planted soil. The experiment was conducted in a field in the Al-Nouriya district of Al-Diwaniyah Governorate in 2023, on a clay-silty soil mixture. The researchers used a Randomised Complete Blocked Design for the factorial experiment. (R.C.B.D) with three replicates.

Slow-release and organic fertilizers are promising alternatives to conventional fertilizers, as both reduce losses by leaching, volatilization and problems of toxicity and/or salinity to plants. The objective of this work was to evaluate the effect of different rates of the organic fertilizer Humato-Macota® compared with the slow-release fertilizer Osmocote® on the growth and nitrogen content in the dry matter of Rangpur lime. A field experiment was conducted in a factorial completely randomized design with an additional treatment (4 x 4 +1). The first factor consisted of four HumatoMacota® ra

Abstract:
Rice-fish farming is a model that is considered suitable to be applied in rice fields, both on a large or limited land as long as water availability is sufficient for rice and fish to grow. In rice-fish farming, there is integration between fisheries and agriculture where integration can improve the efficiency of the supply and use of fertilizer and feed. The research aimed to find the reduction of inorganic fertilizer in integrated rice-fish farming with the rice-fish system to increase fertilizer efficiency.

Two factors were examined in the study: the first is nitrogen fertilization with urea fertilizer (46% nitrogen) using three levels (0, 1.6, 3.2 g plant-1), and the second factor is spraying with three concentrations of ascorbic acid (0, 30, 60 mg l-1).

Abstract:
An important factor, which often limits the effectiveness of current biodegradation techniques, is the poor ability of the microbial communities inhabiting the contaminated environments to degrade the pollutants. Therefore, addition of fertilizers of organic and mineral origin, which trigger the metabolic processes of microorganisms and, as a result, stimulate their growth, is a common practice. The aim of our research was to evaluate the effect of a fertilizer on the abundance of microorganisms during soil remediation. The object of study was a soil polluted by a POP complex, that was collect

Abstract:
Organic sapropel is a high-quality source of soil humus replenishment and is highly effective when applied to degraded and technogenically contaminated soils. The specific conditions of sapropel deposit formation result in a dispersed structure containing 92-98% water. To utilize sapropel as a solid organic fertilizer, its moisture content must be reduced to 60%, which requires significant energy input. One approach to utilizing organic sapropel in its natural moisture state is treating it with a weak alkaline (or acidic) solution to produce humic fertilizers. To ensure a high-quality reaction

The U.S. Department of Agriculture (USDA) has been monitoring the U.S. farm sector's productivity performance since the 1960s. Today, USDA, Economic Research Service (ERS) bases its U.S. agricultural productivity statistics on a sophisticated system of production accounts, drawing data from numerous sources. A notable feature of the U.S. productivity accounts is the input quality adjustment, as some inputs have undergone significant changes in their quality over time. According to USDA, ERS estimates, between 1948 and 2021, total farm output grew by 1.46 percent annually. With total input decl

This study investigates the disconnect between falling agricultural commodity prices and persistent food inflation by applying a Heterogeneous Vector Autoregression (VAR) model to a panel of 203 countries using data from 1961 to 2022. It analyzes the impact of global crops, fertilizer, and oil prices on domestic inflation and explores the asymmetries in the pass-through of global shocks. Results show that fertilizer price shocks significantly influence crop prices, especially maize and soybeans, while production shocks have a weaker effect.

Land-based activities are responsible for over a third of global greenhouse gas emissions, yet the economics of land-use decisions have not been explicitly modeled in global mitigation studies. In this paper, we develop a new, general equilibrium framework which effectively captures the opportunity costs of land-use decisions in agriculture and forestry, thereby allowing us to analyze competition for heterogeneous land types across and within

Estimates of carbon sequestration for timber trees is well documented, while fruit trees are understudied. The few existing estimates indicate that fruit trees and fertiliser management on them, can substantially sequester carbon in coffee monocultures, albeit unlikely to the same extent as timber trees. A carbon investor may thus favour timber. In this light, as programs for planting billions and trillion trees are launched “to save the climate”, a wide range of gender, social, justice and environmental concerns are voiced.
