Methods for predicting a yield of fruit growing in an agricultural plot are provided. At a first time, a first plurality of images of a canopy of the agricultural plot is obtained from an aerial view of the canopy of the agricultural plot. From the first plurality of images, a first number of detectable fruit is estimated. At a second time, a second plurality of images of the canopy of the agricultural plot is obtained from the aerial view of the canopy of the agricultural plot. From the second plurality of images, a second number of detectable fruit is estimated. Using at least the first number of detectable fruit and the second number of detectable fruit and agricultural plot information, predict the yield of fruit from the agricultural plot.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include identifying an agricultural object being associated with a subset of agricultural objects, identifying an action corresponding to a subset of agricultural objects responsive, selecting an emitter with which to perform an action associated with the agricultural object, configuring an agricultural projectile delivery system to activate an emitter to propel an agricultural projectile to intercept an agricultural object.

An expandable tree pot includes a pot body and a pot lip arrangement. The pot lip arrangement is in the form of an accordion-style telescoping structure designed to be expanded from a collapsed position to a fully extended position to increase the height of the pot body from a minimum height to a maximum height to permit a user to continue to use the expandable tree pot upon a tree contained therein growing beyond the minimum height of the pot body.

Some embodiments of the disclosure are directed to systems and methods to treat citrus greening. In some embodiments, one or more samples are taken from a location where citrus greening occurs or may occur. In some embodiments, native microorganisms are isolated and propagated. In some embodiments, the microorganisms include algae. In some embodiments, propagated native algae is returned to an area affected by citrus greening. In some embodiments, the returned propagated native algae is distributed to a concentration of 10 times or more of the original native algae concentration. In some embodiments, the distributed algae increase natural antibiotics and nutrients in the soil resulting in prevention of citrus greening.

Disclosed is a method for overwintering and cold resistance of grapevines, the vines are covered with a biological solidification layer, and the method includes the following steps: placing stems of the vines in rows on a ground, and digging soil between the rows to cover the vines and stems in the rows to form a soil-covered layer; and a thickness of the soil-covered layer is such that a distance from the stems to a top of the soil-covered layer is 50-100 mm; and spraying biological solidification solution onto the soil-covered layer to form the biological solidification layer, where composition and concentration of the biological solidification solution are as follows: 0.5-2 g/L of bean flour, 0.2-1 g/L of xanthan gum, 0.2-1 g/L of cellulose, 0.5-2 g/L of urea and 0.5-2 g/L of calcium chloride. The method is safe, reliable, time-saving, and easy to operate for overwintering of vines.

A device and method for introducing new vegetation into a forest floor includes seeds, seedlings, and/or saplings carried within a plurality of tapered shells having polygonal cross sections, possibly mixed with soil, sand, gravel, fertilizer, SAP granules, and/or water. The tapered shells are inserted into the ground through the hydrophobic layer by dropping or propelling them from an aircraft, or manually pressing on them. One or more holes proximate the bottoms of the tapered shells enable rain water and germinating roots to penetrate into soil beneath the hydrophobic layer. A perforated lid can prevent the seeds or seedlings from being ejected upon impact with the forest floor. A weighted tip can improve penetration of the tapered shells into the forest floor. A plurality of tapered shells can extend downward from a tray or frame. The tapered shell and/or perforated lid can be made from biodegradable materials.

A method and system for managing bearing plants so that their in-ground portions (e.g., root-zones) are clustered together to improve water-use effectiveness; and training their above-ground structures such that their above-ground structures have the wider spacing they require. It is applicable to plants (e.g., vine-like plants including wine grapes) whose trunks can be oriented at an angle other than vertical or which can be otherwise shaped so that their distal ends are not centered above their in-ground portions but rather are horizontally offset from the in-ground portions.

A device for watering a tree comprises a water container, an inlet to receive water into the container, an inlet valve configured to close the inlet to the container when a water level within the container reaches a maximum water level and open when the water level drops below the maximum water level, a pressure relief mechanism to limit a pressure in the container to a maximum pressure greater than ambient pressure, and one or more outlets to allow water to discharge from the container to apply water to a rootzone of a tree in use.

An agricultural machine for arrangement on a vehicle, wherein during movement of the machine in the travel direction an area of soil at least between plants arranged parallel to the travel direction in row crops can be tilled by the machine, wherein the machine comprises a soil tillage tool, which is pivotable back, counter to the travel direction, about an axis of rotation running in a height direction of the machine out of a transverse direction arranged perpendicular to the travel direction and perpendicular to the height direction and/or is movable towards the machine in the transverse direction, an obstacle sensor by which obstacles can be detected, and comprises a control device, wherein when an obstacle is detected the control device can pivot the soil tillage tool back out of the transverse direction counter to the travel direction and/or move it in the transverse direction towards the machine.
