data = pd.read_csv('soil_moisture.csv')
X = data[['temperature', 'humidity', 'precipitation']]
y = data['soil_moisture']

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train a linear regression model
model = LinearRegression()
model.fit(X_train, y_train)

# Predict soil moisture levels
y_pred = model.predict(X_test)
print("Predicted Soil Moisture:", y_pred[:5])
