A computer system obtains, in electronic format, a training dataset. The training dataset comprises a plurality of training images from a plurality of agricultural plots. Each training image is from a respective agricultural plot in the plurality of agricultural plots and comprises at least one identified fruit. The computer system determines, for each respective fruit in each respective training image in the plurality of training images, a corresponding contour. The computer system trains an untrained or partially trained computational model using at least the corresponding contour for each respective fruit in each respective training image in the plurality of training images, thereby obtaining a first trained computational model that is configured to identify fruit in agricultural plot images.

Method for producing soluble potassium sulfate by recrystallization of crude potassium sulfate wherein the crude potassium sulfate contains an amount of potassium, calculated as K.sub.2O, of about 15 wt % or higher, and the resulting potassium sulfate crystalline material conforms with the following characteristics: the amount of insoluble material is less than about 0.05 wt %, a 1 wt % solution of the potassium sulfate has a pH below about 6, and/or 1 pH unit lower than the pH of the crude potassium sulfate, the fraction obtained after crystallization has an average particle size within the following parameters: (i) d90<about 0.6 mm, (ii) d10>about 0.02 mm, and (iii) dust amounts to about 0.4 wt % or less, whereby the resulting potassium sulfate contains more than 51% potassium, calculated as K.sub.2O.

A method for the production of fruit trees including the steps of: grafting of an offshoot or propagation material of the variety to be propagated on a grafting point of a rootstock, to form a tree, planting of the rootstock in a nursery, pot or greenhouse ground and subsequent transplanting of the developed tree in a production ground; wherein the planting takes place arranging the rootstock tilted to one side to form with the ground an angle of pre-set amplitude, smaller than 90° and preferably of 45° and with the offshoot in a substantially vertical position; in the transplanting step the rootstock is arranged in the production ground in a substantially vertical position, so that the trunk of the tree, which is angled in respect to the rootstock, forms a main side branch from which vine-like branches or side branches orientated upwards sprout.

Provided is an apparatus for growing a plant or a fungus, in which struts provided for hydroponic cultivation or the growth of a fungus are kept out of the way. An apparatus for growing a plant or a fungus according to the present invention is provided with: multiple struts 1; brackets 2 respectively fixed to the struts 1; top-opened water passages 3 which are suspended over the brackets 2 and in which a plant P is to be grown; and lids 4 which respectively cover the upper surfaces of the water passages 3 and each of which has, formed therein, multiple holes (pot insertion holes) 41. Each of the brackets 2 projects in opposite directions around each of the struts 1. Each of the struts 1 is arranged at the midpoint of each of the brackets 2, and multiple rows of the water passages 3 are arranged in parallel so as to pinch the struts 1 therebetween. Each of the lids 4 is made from a material that can reflect light from above and can prevent the penetration of the light through the water passages 3.
