Terms and conditions
The Rice Crop Manager provides crop and nutrient management guidelines for rice in irrigated and rainfed lowland environments. The use of this software is subject to the following terms and conditions:
The International Rice Research Institute (IRRI) does not endorse or promote specific agricultural inputs and fertilizers, and it does not guarantee the accuracy of an analysis labeled on commercial agricultural inputs and fertilizers. The software assumes that the
N, P2O5, and K2O analysis labeled on a bag of fertilizer or organic material accurately reflects the content of plant nutrients. Many factors beyond the scope of Rice Crop Manager—such as climate and water management—affect rice yield. IRRI does not guarantee a targeted rice yield will be attained with the provided management guidelines. The content of the software is subject to change without notice.
Limitation of liability
Under no circumstances and under no legal theory, whether tort, contract, or otherwise, shall the Board of Directors of the International Rice Research Institute (IRRI) or any of its affiliates, officers, employees, or other representatives be liable to you or any other person for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, specifically including damages to crops and soil resulting from the application of the software, or for any damages or liabilities even if IRRI shall have been informed of the possibility of such damages or liabilities, or for any claim by any other party. This limitation of liability shall apply to liability for death or personal injury except to the extent applicable law prohibits such limitation.
