Agricultural Kibbutz Avoids Pesticides and Chemical Fertilizing
How does the chemical 2,4-D function as both a weed killer and a lawn fertiliser?
Effectively, how does its effects vary on weeds and on grasses?
Thanks in advance, best answer will be selected.
I’ve never heard of 2,4-D being referred to as a fertilizer. It was first developed as a growth regulator. It can speed up the normal growth of a plant. In minute doses it can be used to bring a plant to maturity sooner. More commonly though it makes the plant essentially grow itself to death The plant matures rapidly to the point of premature death. It’s hardly practical to use 2-4,D as a beneficial because the doses are so small, and the conditions must be just so. It’s more an exercise, for botany and plant propagation students in the lab.
It’s effective as a pesticide on broad-leaf weeds because of their particular physiology, which is different of most grasses. Although it isn’t an effective pesticide towards most grasses it will most definitely kill them under the proper conditions. It’s quite common for grasses to be discolored, and their growth stunted for a while after being sprayed.
It’s an interesting question. I’m looking forward to some of the other responses

Solvent Effects and Chemical Reactivity $157.72 This book presents an uptodate view of theories, practical methods and applications of solvent effects and chemical reactivity in condensed phases. Subjects treated include continuum solvation models, the theoretical basis for the treatment of solvent effects in density functional theory, Monte Carlo simulations of chemical reactions in solution, DFT molecular dynamics simulations, crossing the transition state in solution, valence bond multistate approach to chemical reactions in solution, quantum theory of solvent effects and chemical reactions. The approaches taken as well as the resulting findings are discussed in detail, thus covering a large part of the methodology currently used in this field. Audience: This volume will be useful to graduate students in chemistry, physical chemistry and biochemistry, to research workers with a background in quantum chemistry and quantum mechanics, to pure and applied quantum chemists, and to industrial molecular modellers.

Soil Fertility and Fertilizers: An Introduction to Nutrient Management $161.32 Long regarded as the leading book in the field, this volume provides a basic introduction to the biological, chemical, and physical properties affecting soil fertility and plant nutrition. It covers all aspects of nutrient management for profitable crop production, with particular attention to minimizing the environmental impact of soil and fertilizer management. The "Seventh Edition" has been substantially revised to reflect rapidly advancing knowledge and technologies in both plant nutrition and nutrient management. Crop specific data to estimate nutrient status and needs for many diverse products are provided, as well as example calculations that are routinely used in the market make this a comprehensive resource tool. Nutrient management, water use, and economics are all fully covered. Comprehensive discussions of the development and use of nutrient recommendation systems make this an excellent reference and must-read for soil professionals, technical service providers, extension agents, and crop consultants. |
