Abstract
Methods of promoting the survivability and growth of seeds and seedlings which employ a fertilizer or a synergistic combination of a fertilizer and a moisture absorbing polymer which furnishes a reservoir of the moisture needed for plant growth and also provides a growth medium for soil bacteria relied upon to break down and release nitrogen from the fertilizer molecules. Systems for delivering these formulations and for verifying the delivery of the material.
Claims5
A system for making nutrients and moisture available to seedlings, said system comprising:
- a receptacle composed of a material that is permeable to water, a plant nutrient source in said receptacle, said receptacle having a burst strength and a moisture absorbing composition in said receptacle, the burst strength of said receptacle and the amount and absorptivity of said moisture absorbing composition being so related that the absorption by said composition of an effective amount of moisture will result in said receptacle rupturing and releasing said plant nutrients and said moisture absorbing composition to a seed or seedling.
