In general, Crops in United States were better than average during the monitoring period. This is the key growing season of winter wheat and sowing season of summer crops. The agro-climatic environmental variables include above average rainfall (+14%) and temperature (1.2℃) and below average PAR ( -2%).

整体而言，2016年1-4月，美国作物的整体状况好于过去5年同期平均水平。此监测期是冬小麦的关键生长期，同时也是秋收作物的播种期。CropWatch农气指标监测表明降水偏高14%，温度偏高1.2℃，光合有效辐射偏低2%。

Almost all main winter wheat production states enjoyed good agro-climatic condition with above average rainfall and temperature: Kansas (+7% rain, +1.7℃), Oklahoma (+33%, +0.9℃), Texas (+42%+0.3℃), Washington(+24%+1.8℃), California( +16%, +1.4℃) and Montana (+116%, +3.1℃). The recent grip of drought appears to have receded. The spatial distribution of NDVI profiles indicate that 90.8% of crop areas had average NDVI or positive departure before Mid-March. Only 9.8% of the agricultural areas (north Texas, Oklahoma and Kansas) were showing slightly negative NDVI departure. As mentioned in the section on disasters, torrential rain were occurred in  Texas neighbouring areas. With the exception of Illinois (-21% RAIN), Missouri (-6% RAIN ) and Indiana (-5% RAIN),most of the Corn Belt recorded average or above average rainfall including Iowa (+6%), Ohio (+5%),Wisconsin (+13%), Minnesota (+49%), Nebraska (+37%) and North Dakota (+113%). Abundant rainfall was favourable for summer crops sowing and their early growth stages.

监测期内，温暖湿润的农气状况在冬小麦主产州占据主导地位，如堪萨斯州（降水偏高7%，温度偏高1.7℃）、俄克拉荷马州（降水偏高33%，温度偏高0.9℃）、德克萨斯州（降水偏高42%，温度偏高0.3℃）、华盛顿州（降水偏高24%，温度偏高1.8℃）、加利福尼亚州（降水偏高16%，温度偏高1.4℃），蒙塔纳州（降水偏高116%，温度偏高3.1℃）。监测期内，干旱发生的区域持续减少。NDVI距平聚类图监测表明，三月中旬前90.8%的农作物区的NDVI较往年同期平均水平偏高。仅仅9.8%的地区NDVI值较往年同期平均水平偏低，如德克萨斯北部地区，俄克拉荷马州与堪萨斯州。在德克萨斯及其邻近地区因飓风而发生较大的洪涝灾害。除伊利诺伊、密苏里和印第安纳州的降水较往年平均水平偏低21%，6%与5%之外，玉米带内大部分区域的降水好于往年同期平均水平，如艾奥瓦州、俄亥俄州、威斯康辛州、明尼苏达州、内布拉斯加州与北达科他州的降水分别偏高6%，5%，13%，49%，37%与113%。充足的降水为秋收作物的播种与早期生长创造了良好条件。

Although agronomic indicators show average CALF (0%), the US wheat planted area is still 5.6% below 2015. The biomass production potential was 19% above average and CropWatch forecasts US average winter wheat yield for 2016 to increase 1.6% above the previous year. Altogther, CropWatch puts US wheat production at 54.3 million tons, 4% down from 2015. If the favorable weather continues, final yield is expected to be higher than this forecast. 

尽管监测期内的作物种植比例与往年同期平均水平持平，但是冬小麦种植区的播种面积较2015年同比减少5.6%。潜在累积生物量较往年同期平均水平偏高19%，同时，CropWatch单产监测表明小麦单产较去年同期平均水平偏高1.6%。CropWatch预测2015-2016年美国小麦总产为5430万吨，较去年同期平均水平偏低4%。如果小麦产区良好的农气状况持续，CropWatch预计最终的小麦单产将高于当前的预测值。
