Report Industry Investment Rating - Not provided in the given content Core Viewpoints - In June 2025, most major global agricultural product producing areas were stable, but some regions faced risks due to weather. The overall weather in the US soybean and corn producing areas was good, with short - term dryness in the Midwest being alleviated, and the yields remained stable. The cotton - growing areas in the US had favorable hydro - thermal conditions, but extreme precipitation in Texas in early July might have an impact. The palm oil - growing areas in Southeast Asia had a good overall growth environment, but a sudden drop in precipitation in Sumatra required attention. The rapeseed - growing areas in Canada and Australia had some issues, and the temperature in the Xinjiang jujube - growing area was generally normal, while high temperatures in Aksu from May to June needed to be monitored. Europe faced risks of drought and wildfires due to a heat dome from late June to early July, and strong convective weather occurred after the heat dome collapsed in July. The weather in North America in the coming month would be conducive to crop growth [1]. Summaries According to Related Catalogs Global Key Agricultural Product Yield Estimation - **Monitoring Scope and Method**: The monitoring covered the US soybeans, corn, cotton, Canadian rapeseed, Australian rapeseed, and Southeast Asian palm oil in June, using data from 2005 - 2025. It combined satellite remote sensing, meteorological data, and field observations, with 24 key indicators. A self - developed yield model was also constructed, which used multi - spectral and hyperspectral remote sensing data, combined with meteorological and historical yield data, and was trained and optimized through a deep - learning model [6][7][13]. - **Yield Estimation Results**: The yields of US soybeans and corn were basically stable, with a slight decline in the overall yield per unit area that could be ignored. In the Canadian producing areas, the crop growth in the Manitoba region in the east was affected by drought, slightly dragging down the overall yield per unit area. The Australian rapeseed yield was slightly revised upward, but it was still worse than the historical average. The US cotton maintained good growth, but excessive precipitation in June and extreme precipitation in Texas in early July might have an impact [14]. Global Key Agricultural Product Growth Monitoring - **Palm Oil Producing Areas in Malaysia and Indonesia**: In June 2025, the growth environment indicators in the palm oil - growing areas were generally in good condition. Vegetation indices in different regions showed small fluctuations. Precipitation and soil humidity had regional characteristics, with a sudden drop in precipitation in Sumatra posing a potential risk. The temperature rose slightly, remaining within the suitable range for palm growth [17][18][25]. - **US Soybean and Corn Producing Areas**: In June 2025, the overall weather in the US soybean and corn producing areas was good, but there were regional differences in precipitation. North Dakota and Nebraska had poor soil moisture due to less precipitation, and North Dakota's crop growth was negatively affected. Vegetation indices in different regions showed significant differences related to hydro - thermal conditions. Soil humidity generally increased, but it decreased in Nebraska [26][31][35]. - **US Cotton Producing Areas**: In June 2025, the growth of cotton in the US producing areas was mostly on the rise due to good hydro - thermal conditions, but excessive precipitation in some areas had an inhibitory effect. Vegetation indices in different regions showed different trends, and soil humidity was generally higher than normal, with the increase in the deep layer being more obvious [38][39][41]. - **Canadian Rapeseed Producing Areas**: The vegetation index in the Canadian rapeseed - growing areas slightly decreased, and the soil moisture risk in Manitoba was relatively high [1]. - **Australian Rapeseed Producing Areas**: The growth of rapeseed in Australia was poor, and there was a high risk of yield reduction in South Australia and Victoria [1]. - **Xinjiang Jujube - growing Area**: The temperature in the Xinjiang jujube - growing area was basically normal, but the high temperature in Aksu from May to June needed attention [1]. - **Recent Formation and Collapse of the Heat Dome in Europe**: A heat dome formed in Europe from late June to early July, causing extreme high temperatures, drought, and wildfire risks. After the heat dome collapsed in July, strong convective weather occurred, and it might form again later [1]. - **Historical and Future Weather Analysis in North American Producing Areas**: The weather in North America in the past month and the extreme precipitation in the southern US were analyzed. The weather in North America in the coming month would be conducive to crop growth, with improved precipitation in the US Midwest and possible alleviation of soil moisture in the Canadian rapeseed - growing areas [1].

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The report is in the north - south alternation blank stage of South American production determination and North American sowing. South American production has little fluctuation, and North American sowing is ongoing with no yield estimates made. The overall drought - flood differentiation in the US is obvious, with severe drought in the central part and waterlogging in the southeastern cotton - producing areas [1] 3. Summary by Relevant Catalog Global Key Agricultural Product Growth Monitoring - Malay and Indonesian Palm Oil Producing Areas - Vegetation index is generally stable with regional differentiation. Precipitation has increased across the region, with some areas experiencing excessive water. Temperature has minor fluctuations and is suitable for palm tree growth. Only the potential impact of excessive water on vegetation in Kalimantan needs attention [7] - In April 2025, the vegetation index in Malaysia and Indonesia's palm oil producing areas remained stable overall, with slight differentiation in some areas. For example, the EVI and NDVI in the Malay Peninsula increased compared to the previous 20 - year average [8] - Precipitation in all producing areas in April 2025 was higher than the historical average, and soil moisture increased accordingly. The Malay Peninsula and Kalimantan had significant precipitation increases, while Sarawak and Sabah had outstanding soil water storage capacity [8][10] - In April 2025, the temperature in the producing areas showed a "slight decline and then stability" trend, all within the suitable range for palm tree growth. The stable temperature and sufficient precipitation are beneficial for palm fruit bunch development and oil synthesis [15] North American Sowing Environment Monitoring - In the past 5 months, the precipitation in the US has shown obvious differentiation, with more precipitation in the east and south and less in the central part. In the past month, the precipitation in the east and south has further increased, and the precipitation in the central part has changed differently in different regions [17] - As of the week of May 6, about 15% of the US soybean - planting area, 20% of the corn - planting area, and 20% of the cotton - planting area were affected by drought. The drought area in the central part has increased compared to last year, but the drought degree and intensity in 2025 are less than those in 2023 [20][23] - As of May 8, the excessive precipitation in the southeastern US has caused some flooding, mainly affecting the cotton - planting area, and the short - term impact will continue [27] US Soybean and Corn Producing Areas - Precipitation in the central and southeastern parts has increased significantly, providing sufficient water for the core producing areas. Some areas such as Arkansas, Kentucky, and Tennessee have more than doubled their precipitation compared to the historical average [34][35] - Soil moisture has increased across the board, and the core areas have prominent deep - layer water advantages. Most producing areas have sufficient soil water, but attention should be paid to the drainage of local low - lying plots [36] - In April, the temperature in each producing area showed a mild upward trend, with the highest and lowest temperatures generally higher than the historical average. Most areas are within the suitable temperature range for crop growth, but attention should be paid to the accumulated temperature in the northern areas [40] US Cotton Producing Areas - Precipitation in the southeastern part has increased significantly, while the western part continues to be seasonally dry. Excessive precipitation in the southeastern part may affect the sowing progress, and the western part needs to strengthen irrigation management [41] - Soil moisture in the central and southeastern wet areas is high, while the surface water in the western part is insufficient. Except for the western arid area that depends on irrigation, the soil moisture in the central and southeastern producing areas basically meets the needs of cotton growth [47][48] - The temperature in the producing areas shows a trend of "general increase and higher in the south". Mild temperature increase is beneficial for cotton budding and flowering, but the southern areas need to prevent the adverse effects of high - temperature and drought on boll setting [50]
