“…That manure enhanced colonization indicates that AMF are important in highly manured soils. The results suggest that banded manure might be used to replace mineral fertilizer as a source of starter P, as suggested by Schröder et al (1997)…”

“…Starter fertilizer was found to increase the yield of corn on soils with medium (but not high) P availability that also received manure during the trial years. In the Netherlands, starter P fertilizer increased corn yield by 8% on manured soils, and this was attributed to the need for P close to the roots 5 to 7 wk after planting (Schröder et al, 1997). In south‐coastal British Columbia, at least 20 to 30 kg P ha −1 of starter P fertilizer is routinely applied to silage corn crops after applications of ∼50 kg P ha −1 as dairy slurry because starter P seems to provide better early growth and more consistent end‐of‐season results (Bittman et al, 2004).…”

Starter Phosphorus and Broadcast Nutrients on Corn with Contrasting Colonization by Mycorrhizae

et al. 2006

Early P nutrition in corn (Zea mays L.) is important for early growth and arbuscular mycorrhizal fungi (AMF) may help juvenile corn plants access soil P. The role of AMF colonization in manured soils and the impact of AMF on the need for starter P is not well known. This study was designed to assess the response of corn with contrasting levels of AMF colonization to low rates of starter P under inputs of broadcast liquid dairy manure or N and P fertilizer. The study was conducted on a high-P-testing soil in south-coastal British Columbia. Contrasting AMF colonization was achieved by growing corn either after corn or after fallow. Both AMF colonization and starter P improve early growth and, to a lesser extent, final harvest even on a relatively high P soil receiving a heavy application of P as broadcast liquid dairy manure or fertilizer. The effects of AMF colonization and starter P were additive, so both contribute to maximum yield. Our study suggests that practices favoring AMF colonization will help juvenile corn plants take up P. While strategically placed low rates of starter P were beneficial for juvenile plants, these treatments were less effective than conventional sidebanding at 30 kg P ha 21 because the effect did not carry forward to final harvest, even in corn that was well colonized by AMF. Therefore, better nutrient strategies and AMF colonization are needed to ensure that corn crops will gain sufficient P with minimum starter mineral fertilizer on manured soils.

“…The concentrated band of fertilizer reacts slowly with the soil so that the P remains available longer than P mixed in the soil. The practice of side‐banding P is commonplace even on high‐P soils receiving manure (Withers et al, 2000; Schröder et al, 1997; Jokela, 1992). A recent paper from Denmark reported that the typical practice of side‐banding commercial P fertilizer after manure application leads to annual P accumulations on silage corn soils of 15 to 25 kg P ha −1 (Petersen et al, 2010).…”

Efficient use of manure nutrients by crops is necessary to minimize losses to the environment. This field study examined the possibility of replacing side-banded mineral P with precision-placed high-P sludge (6.2-11.0% dry matter) obtained after settling dairy manure slurry. The sludge was injected at about 30 kg P ha (36.0-51.2 m ha) into the soil at corn row spacing, and the corn was planted 5, 10, and 15 cm beside the injection furrow. Controls included no added P and side-banded commercial P fertilizer. The treatments were tested on corn with low and high root colonization by arbuscular mycorrhizae (AM). The study showed that sludge did not impede AM root colonization, corn germination, or seedling growth. Corn plants with both high and low levels of AM colonization responded to the sludge from the three-leaf stage and showed the greatest benefit at the six-leaf stage. Corn responded more to sludge placed at 5 than at 15 cm from the corn rows, whereas the response at the 10-cm spacing was intermediate. There was little difference in seedling growth or final harvest parameters between the side-banded fertilizer P and the 5-cm sludge treatment. The results show a new way to use manure nutrients, namely precision-placement sludge for corn. This may obviate the need for chemical fertilizers for improving farm nutrient balances. Other anticipated benefits are less energy use for hauling and injection of the sludge fraction and reduced risk of nutrient loss by runoff and volatilization (ammonia) and nuisance odors due to injection.

“…Kallela (2006) reported that banding application of broiler manure increased yield compared with broadcasted treatments under the condition that soil N concentration was low prior to the growth season. Schröder et al (1997) found that cattle manure, injected more closely to the maize plants, increased dry matter and nutrient uptake due to the better N and P availability. Plant P uptake is largely affected by root traits and a longer root system has often been associated with greater capacity for uptake of soil P ( Lambers et al, 2006; Richardson et al, 2011).…”

Sewage sludge (SS) can be used as an alternative fertilizer in agriculture. It is normally broadcasted and plowed into soil, but it is not clear if it has a potential as a placement fertilizer. A rhizobox experiment was conducted to investigate the placement effect of SS and mineral nitrogen (N) fertilizer on shoot and root growth as well as nutrient uptake of spring wheat (Triticum aestivum L.). The treatments included localized SS, mixed SS, localized SS and ammonium, localized ammonium, and a control without addition of SS and ammonium to examine the effect of SS placement and, further, if ammonium co-localization would enhance the placement effect. The results show that SS fertilization improved soil N and P availability, which significantly increased plant N and P uptake and enhanced shoot growth, while root length was significantly reduced compared to the control. Localized SS increased root proliferation in the placement region, resulting in enhanced uptake of P from the SS patch compared to homogenous application. However, co-localized application of ammonium with SS significantly depressed plant shoot and root growth. Localized ammonium markedly restricted root proliferation in the placement region and reduced soil pH in both bulk soil and placement region, contributing to decreased nutrient uptake and plant growth.
