Abstract: Embodiments provided herein include systems and methods for providing crop management. One embodiment includes providing a yield goal for a field from a grower, receiving tissue samples for at least one crop in the field and a seed population for the field, and interpolating individual field grid point values of the field. Some embodiments include predicting a growth plan of water and nutrient applications to meet the yield goal, based on determined sufficiency levels and individual field grid point values of the field, predicting whether the growth plan includes a component that is unlikely to be met, and in response to predicting that the growth plan includes the component that is unlikely to be met, providing the component that is unlikely to be met to a user. Some embodiments include providing an option for the grower to alter the yield goal such that the component is likely to be met.

Abstract: An audio output device (101) is configured to transmit an audio signal to an external power amplifier (107). The transmission of the audio signal can be accomplished by means of a wireless transmitter (401) or standard audio cable (103). The power amplifier (107), a low voltage power supply (111), and in certain embodiments a wireless receiver (109) are commonly housed in a weatherproof enclosure. In one embodiment of the invention, the amplified audio signal and low voltage power provided by the low voltage power supply (111) are transmitted by means of a common cable to a lighting and sound unit (115).
