SYSTEM AND METHOD FOR CROP THINNING WITH FERTILIZER
First Claim
1. A system for crop thinning with fertilizer comprising:
- a camera configured to capture images from an agricultural field;
a sprayer configured to selectively spray fertilizer on said agricultural field;
a computer coupled with said camera and said sprayer wherein said computer is configured to obtain an image from said camera;
process said image to determine locations of plants in said image;
determine a first set of locations of plants to spray with said fertilizer to kill said first set of locations of plants and determine a second set of locations of plants to not kill;
set a first amount of fertilizer to spray said first set of locations of plants with that is sufficient to kill said first set of locations of plants and spray said first set of locations of plants.

Abstract
Utilizes machine vision to thin fields, for example by selectively spraying plants with enough fertilizer to kill the plants, for example to maintain a minimum distance between plants or to enable remaining plants to grow in a pattern, for example two dimension diamond pattern. The use of fertilizer to kill plants has the benefit of fertilizing the field, i.e., the remaining plants not to be killed, at the same time. This unexpected result which occurs in the thinning and simultaneous fertilizing of a field is based the discovery that immature plants are more sensitive to fertilizer than mature plants. The system and method eliminates the need for harmful chemicals and mechanical thinners and may be retrofitted onto existing spray systems and platforms, thus eliminating herbicides and thinning machinery.
