The Fertility of Agricultural and Non-Agricultural Traditional Societies

Population Studies, 1993
A comparison of demographic data from a sample of traditional, natural-fertility societies demonstrates that the mean total fertility of populations which practise intensive agriculture is significantly higher than that of foragers and horticulturalists.

Role of Fertilizer in Agriculture

1985
Agriculture has been constantly evolving since the initial agricultural revolution some 10,000 years ago. This initial revolution was the result of domestication of plants and animals to serve man’s needs and led to the generation of food production in excess of the requirements of the agricultural population.

Semi-Automated Agricultural Fertilizer Applicator

IOSR Journal of Agriculture and Veterinary Science
In this paper, aiming at the current advancements in agricultural technology, a semi-automated fertilizer dispensing system is presented to improve crop yield through targeted and efficient nutrient delivery. Designed specifically for crop-producing areas, this system offers a cost-effective alternative to conventional manual methods.

Population growth, soil fertility, and agricultural intensification

Journal of Development Economics, 1994
This paper presents a renewable resource model of soil fertility with a nonconvexity in the net benefit function. In this setting, recurring cycles of cropping and fallow can be the optimal soil management strategy. The model is used to illuminate the Boserup discussion of agricultural development, in which population growth leads to agricultural ...

Potash fertilizer to agricultural based economies

2018
Potash is an indispensable element in agricultural development and innovation. It is relatively cheaper to mine, produce and be imported compared to other fertilizing materials such as nitrogen. This makes potash a viable material for agricultural based economies such as New Zealand.

Optimizing Fertilizer Applications for Organic Agriculture

2006 Portland, Oregon, July 9-12, 2006, 2006
If organic agriculture is to be sustainable, it must consider management strategies that apply over the long term. This paper presents a linear model for optimally scheduling land application rates once a system has approached steady state. Multiple fertilizers and amendments can be included, and solutions can be optimized by minimizing nitrogen ...

Nitrogen fertilizer use in rainfed agriculture

Fertilizer Research, 1984
Agronomic efficiency (AE) is defined as the increase in economic yield of a crop per unit fertilizer applied. Components of AE are physiological efficiency and apparent recovery fraction. The latter can be further separated into uptake efficiency and availability index.
